Show more about upcoming games - including release dates.
Right now it is very difficult to what to look for and when within the store, and the blog posts aren't frequent enough to keep users informed of this either. I feel this sort of damages the platform and the user experience because it doesn't give users the hype necessary to keep interested in an especially nascent platform.
Even if release dates where vague, down to month/season/quarter or whatever, having an official place to see what's coming and when serves so much to everyone -- but especially to those who have run out of new stuff to play on the system.
On top of that, there's people like myself who sometimes have to plan to get new things, sometimes i don't know what's coming and then don't have anything really set aside to toss at it, so a better "heads up" spot on the store would let me know when to skip the mignon one week if you know what i mean :)
