I have very low expectations for this. Everyone who wants this game has it by now, more or less. So who is the market for this? Former Wii owners? 3million or less I say.

It'll probably do pretty well, 3 million on Xbone and 6 million on PS4

Yeah 6 million seems possible between both. It sold 20 million after all. 3 is more likely.

PS4 version alone will to 9 million this year.

Bundulu will sell like hot cakes... the best selling bundulu of the year.

8 - 10 Million combined.

i got high expectations for this guess b/c i didnt play it last yr, i believe 10M by yrs end for both xb1 and ps4 and 20M lifetime

I am doubtful that it does all that great, though it has a clear shot at #1 remaster. If they added content it would do huge numbers.

I'll say 3 million between both consoles.

I think the PS4 version will outsell xb1 by 3:1 - as xb1 owners will get Halo MCC and Sunset Overdrive instead

I think it'll do well. I intentionally skipped GTA V on 360/PS3 because I was certain that there would be a next-gen/PC port eventually. I doubt I'm the only one.
