Just a little idea that popped into my head,
What about a (stripped down. 3-5-10? songs) internet game of Blitz?
Quite a few arcade games originated from this sort of thing, or used it to get better known. Games like Alien Hominid, Trials HD, Super meat boy, N+ and others started as games on the internet. and from what i can tell those sold pretty damn well.
So the basic idea would be an almost completely stripped down version (just quickplay, a few power-ups and only a couple of songs) spread across lots of sites like Newgrounds.com , Kongregate.com and other internet game sites. Including a loading screen that tells people they can get Blitz for XBL or PSN.
dunno, just an idea that popped into my head. I think it can really help get people to know about this game and how fun it is. what do you guys think?
