There's the same ol' same ol' in most of those.... They point at "more power", well duh. Of course systems are going to get more and more powerful, otherwise I'd wait for things to come out still on my good ol' Atari 2600.
What we really need is a revolution in gaming technology for the console. Something that provides a new level of interactivity, be it from a 3D projection, to a Virtual Helmet set. ANYTHING would be an improvement over the joystick games of current. I mean look at it this way, we've had the same type of games coming out for years now, nothing new, nothing challenging as far as pushing the limits of what we can do. Why not give the home console gamer something they'll be addicted to? Perhaps an interactive environment where we're pumping sensations to them that they actually FEEL, SMELL or even TASTE. To long has the gaming world been in our rumble packs, ears, and eyes, something has to push forward, and I just wonder when the gaming companies will notice that.
