Like a lot of people I have the 3GS and am waiting on the first app that advertises that it supports and takes advantage of the 3GS hardware. The first developer to support OpenGL 2.0 be able to make that claim will enjoy a great boost in sales from 3gs owners.
I think you have a point. I have a 3G S and after reading this article, I'm almost certain to get this game: http://www.pocketgamer.co.uk/r/iPhone/Worms+%28iPhone%29/news.asp?c=14193
I think there are more non 3gs costermers at the moment and it would be a sure sale for you I would not pick it up because I would be getting less for the same money 2xl motocross snuck that by me and i'm a little bitter because if I had knowen I would have waited for price drop my fault for not reading carefully though
