All speculation from crappy sites. Forbes articles seem pretty reliable, less click bait.
I'm not saying it's not true, but they have no evidence of it whatsoever other than it being in the code. Saying it will happen this month is pretty negligent of them without stating a source.
Those exact same sites were wrong about the Thanksgiving event(bird spawns, double coins, etc) and constantly saying PvP, legendaries, and trading is coming "sooner than expected!" :)
