What's next?

They'd need to release groudon with precipice blades to even be able to compete with machamp against Dialga as without precipice blades, groudon needs clear weather to be even with machamp DPS wise, and even then, no one wuld spend hundred of RC to max level a Groudon for only even DPS in weather when machamp provided always consistent top 1 or 2 in DPS (So basically machamp beats groudon w/o PB in all scenarios practically speaking)

Dont think Ralts will get a CD unless they give it misty terrain, which they haven't given status moves to pokemon unless absolutely necessary like with slaking (and even at that it wouldn't elevate its relevance, nothing can compete with dragons weak to dragon type aside from very specific instances like ice on the double weak rayquaza and gengar and SB mewtwo agaisnt Giratina, machamp and fighting types handle dark a lot better than gardevoir can leaving gardevoir in the exact same spot at it is now, hard counter to double fighting set raid boss machampand part time gym speedbump) and Gallade being male locked with requiring a dawn stone I think safely excludes it (likely they will add ever special evolution item from gen 4 as they did the newly added ones for gen 2). I think Bagon or Trapinch are far more likely candidates, and if they're going to make a special item evolution pokemon CD, I think the 2 most likely ones would be either Togepi or Rhydon but not overly confident those would get them.

I think we can see beast raids days in the future, probably spark or soemthing for Raikou given what they did for zapdos, maybe a better fire move on Entei and literally anything would be unable to help suicune because its stats are defense oriented. but shiny release is better pass using motivation than anything

making Suicune Shiny is all the tweaking it needs to sell raid passes to the vast majority of players

Something I'm kinda hoping is that during December, like last year, there could be Water and Ice types spawning everywhere, including Gen 4 Pokemon. However, though, if that's the case, I don't know what the special Pokemon could be, but even though they're not Christmas-themed, I do have a couple of guesses: Kecleon or Smeargle.

Shinys are always good incentive for raids. I say split december in half for groudon and rayquesa, maybe some special raids thrown in (delibird raids with double prizes).

No matter how you slice it ralts makes the most sense for the next CD regardless on if the move is a fairy type or even relevant. I'd like to see galade released with Some CD research tasks giving dawn and dusk stones since a few Pokemon use them in evolutions from here on out.

Raid days are a blast but I'd rather have them only for a good reason. With monthly changes for CDs and special research they are already running into corners on what would be good, hence all the speculation on our part. If RDs become a monthly thing then they will ultimately become stale too

Right now, there's three things I'm hoping we'll see sooner rather than later, yet Niantic has been silent concerning all of them.

1. The CP rebalance. It's been weeks since it was initially released for all of 10mins and then reverted presumably due to the bug where all the Mons whose max health increased were missing hitpoints. That seems like it would have been an easy fix, and yet here we are. It almost makes me wonder if Niantic is doing further tinkering with it.

2. Introduction of new moves from Gen IV. There are a bunch of datamined moves added in with Gen IV, and yet none of them can currently be learned. Setting aside the unreleased Mons, even ones currently available to us can't learn the new moves (Kingler with Crab Hammer for instance). Unlike the new moves with Gen 2 and 3 which were immediately available when those Gens went live, these moves are still unavailable for some reason.

3. The long-awaited evolutions for the multitude of Mons from Gens 1-3. Rhyperior, Tangrowth, Togekiss, Electivire, Honchkrow, etc. None of them were available when Gen 4 went live and, so far, they haven't trickled out with the small release waves of new Gen 4 Mons. I had (incorrectly) assumed that we'd get evos that corresponded with the different release waves: Honchkrow, Mismageus, Weavile and company with the Halloween event, Yanmega with the bug event, and so forth. I'm hoping Niantic will give the new evos the green light soon.

As for Community Days, I would love to see a Ralts CD that lets us evolve into both Gardevoir and Gallade. Perhaps both of them could get a different special move.

I'm also hoping that Dialga and Palkia follow after Giratina. Given how underwhelming Giratina is in Go (including it's Origin form, assuming it has the same moves), the dragons would be a breath of fresh air in the raid scene.

Just a quick note that "tweaking" Suicune does nothing for its usefulness. With 180 base attack stat, WF/HP doesn't get its DPS to anywhere close to good enough. It's very tanky post rebalance and the hope of its usefulness lies in some bigger change that gives value to that tankiness.

But as people said, shiny makes it plenty interesting for RD.
