Sonic: Good point.
That said, Rev = "GCN but twice as powerful." Am I right? IGN seems to think so. Twice the power of the machine that ran RE4 is just fine for $100-200 IMO.
It should be noted that yes, it will be less powerful than Xbox 360 or PS3... but what do those consoles offer beyond their higher prices and sexier graphics? Take a gander at the MGS4 trailer.
Nothing in it couldn't be done on the current generation gameplay-wise, it's only graphically in another league.
Perfect Dark Zero could have been for Xbox. So could Oblivion, albeit less detailed. The wildly popular Geometry Wars would run on PS1, or hell, SNES.
Basically, Nintendo knows that there is a market for high-end systems and this time they've decided to bow out of it. They have a low-cost system that
will have lots of developer support (including IMO the best publisher in the industry, ahem, Nintendo themselves) and appeal to the non-gamer, and to those who want an all-in-one box.
It'll probably be more readily available than a console with a tri-core CPU, too.
The most powerful console doesn't always win; it's the one that sells the most.
If Console A has sold 10 units, and Consoles B and C have sold 3 units combined... which console will get all of the support?
