Let's break the argument down. The first debate is centered around the never ending console vs PC gaming argument. We're willing to say that consoles have already won this battle. The majority of games are played on consoles, therefore the majority of the money goes to console based publishers and developers. Does that mean PC gaming is dead? Not really. There will always be a demand for (as Becky mentions on Ian's blog) "'lean forward' desk-and-chair-gaming like The Sims, WoW and Age of Empires" as opposed to "'lean back' sofa-gam[es] like GTA."
The second debate regards the future of MMOs on consoles. In the quote we mentioned earlier, Ian cites the lack of non-intrusive text input devices as a sign that MMOs on consoles will never reach the popularity of games like WoW on the PC. We disagree. Voice, no matter how intrusive, is much more efficient than keyboard based communication. The real issue that has, in the past, limited the popularity of MMOs on consoles is the lack of demand for MMO games. The original Xbox Live was used by a tiny percentage of the total number of people that bought Xbox consoles. With the Xbox 360 (and other next-gen consoles) an larger percentage of "connected" consoles will likely result in a market big enough to support several subscription based MMOs.
