The latest issue of EGM has an interview with Randy Pitchford of Gearbox, and has some nice things to say about the Wii:
"I think the Wii is awesome! It is just that what makes it awesome isn't about computing power-it's about interface, accessibility, usability, and how we think about playing games and interacting with them."
"...we can be a bit wasteful on the Wii and be really competitive with other Wii titles." (Speaking on the difficulty of programming and available resources)
There's more but I'm not going to type any more. Some else can, though

Sounds like we'll be getting our share of squad based FPS games. Yay!
