Sales...hmmmm
Consoles - a little bump in sales but I don't think it will be much of a system seller.
Software - the game will be an instant hit and will I reckon sell through to about 25% of the console base. I'd hope though that they do the release properly and would possibly favour selling the games separately rather than bundling all 3 together. They also wouldn't need to be released at the same time......i'd just love to play them again.
