The PlayStation 4 is out in a week, and I think it's safe to say that there's been a fair amount of buzz surrounding it. There's also been a fair amount of buzz surrounding the planned launch titles, including the upcoming KNACK.
KNACK's Quest is actually a companion app that lets iOS players collect items through a match-3 game, then send those items to the main console title. Match-up a bunch of different parts to make KNACK bigger - using super moves to help clear the screen when appropriate - and complete each level by getting the unlikely hero to his maximum size. Then you can send some of the goodies you've earned over to the PS4 version to give the big guy an edge. At least that's the plan. As of right now the Item Share feature isn't available but according to Sony it'll be in the next update, which I'm assuming will be right before or on the console's launch day (11/15).
