And you will be able to play NES, Gensis, and SNES games. I will buy a Wii for sure. PS3 I am not so sure of, I havent really touched my PS3 since I started back up WoW.
I'm sure you haven't :P
But I agree, having the option to download and play old games is a huge selling point for the Wii for me (Whee for me hahaha!). Meanwhile all we've really seen of the PS3 is tech demos from last years E3. They looked purty and all that jazz, but we didn't see any actual gameplay footage. If I remember correctly, Sony did say actual gameplay graphics would be on par with the tech demos, but until I get some real gameplay footage I'm going to remain skeptical.
There is also the problem of games. I haven't heard of any in development that pique my interest. Sure, Squeenix plans on continuing the main FF series on the system, but if FFXII is reflective of where the series is headed then I think I'll pass.
Not to mention a heavy price tag which means I will not for any reason be buying it until a price drop. Around $250 I'll begin to consider.
And on a completely unrelated note, I will be calling the Revolution the Wii because I think it is so stupid it's funny. "Do you have my fucking Wii yet, bitch?!" Heheh :P
