Wii Pals had an interview with John Romero. This guy is best known for his work on games like Wolfenstein 3D, Doom and Quake. They talk about games and consoles.
Here's a snip about what he believes will happen to the console and PC gaming market:
JR: Right now MMOs, mobile and PC episodic are really polarizing into the newest most important segments in gaming. Next-gen console is big but its future isn’t too bright with the emergence of cheap PC multi-core processors and the big change the PC industry will go through during the next 5 years to accommodate the new multi-core-centric hardware designs.
My prediction is that the game console in the vein of the PS3 and XBOX 360 is going to either undergo a massive rethink or go away altogether. The Wii has the perfect design for a console that doesn’t pretend to be a PC and is geared more toward casual gamers than hardcore gamers. The hardcore gamers are going to either be playing on their PCs or a new PC-like platform that sits in the living room but still serves the whole house over wifi, even the video signal.
