Well, here we go again. Haven't heard anything about this one for a while. There's a new video up on the Phantom
here
The impression I get is that it's a pay-per-view gaming system with no physical game media. While having demos online (something that would motivate me to get XBL) is a good idea, I fail to see how a large game can be distributed in this manner. Given that we're getting into games that are filling a good chunk of a DVD, you're proabaly looking at a minimum size of 1 Gb for a modern console game. Even with an uncharacteristically fast cable or DSL connection, this would take far too long to download...
And maybe it's just me, but has there EVER been an "upgradable" console that worked? Look at the Sega CD, Sega 32x, etc. About the ONLY thing I can think of that took off as an upgrade is the N64 ram expansion, and even then only because people wanted to play Majora's mask and DK64. The reason I like console gaming is that you don't have to buy more hardware after the initial investment, and your game performance is consistent.
But, it will be the gaming public who will decide if this goes the route of the Xbox or the 3DO.
