Smash: 1.8 million. COMG ration will likely be between 1:1500 and 1:2500. Unless it's some kind of really low anomaly, that's where it'll be, and at 1:2000 that would put it at 1.8 million, not even all that outlandish.
Switch 300k. You gotta figure it's going to do better than Pokemon's week by a pretty good amount.
PS4 40k. A slight jump from the previous week as the holidays approach and the sales takes effect.
Just Cause 10k. I dunno. Can't be much higher, but even a decent COMG ratio would give it 10k.
