Last week I got the 35 balls and 2000 dust, which was the 1500 dust for 50K and the 500 dust for 25k. This week, 1500 dust and a 10k egg and 3 silver pinups, which isn't allowed per the rules from last week, so I don't know, other that it seems to be in flux. The 10k egg hatched to a 11/10/10 shine (s/a/d). At least it came with some candy, and it might fall below 1500 if evolved. (This site's CP calculator wouldn't let it evolve, but the Luxury comes out to 1577. Possibly if traded.)
I suspect they are tweaking this reward on the fly. No idea what to expect now.
