I'm with Tindytim on this.
If Nintendo kills the DS Lite and makes the DSi the defacto DS, then I will go with the PSP. The DSi is nothing but a bid to grab more money. You'd think selling 100 million+ units would be enough for them to do something to give back to that loyalty and enthusiasm(like listen to their fans/users and release more A+ titles!!), but nooooo, we get this craptastic update (a 0.3 megapixel camera?!? on a $170 handheld?! WTH?!)
I'm seriously hoping that the rumor of a 4th version of the PSP with a slide-out touchscreen isn't a rumor and Sony brutally takes back most of the handheld market share. The loads of shovelware and poor quality big name titles (Zelda Phantom Hourglass ugh...,etc.) is bad enough, but this?....
Oh yeah, LONG LIVE GAME BOY ADVANCE GAMES!!!
