It's all about MS PR bable....sections it really isn't a huge deal, what makes it a huge deal is MS blabing for the last 2 years that blu-ray was a waste and DVD9s will be good enough for this generation.
ridiculous,
the reason they did not use another disc technology was never because the space would/could not be utilized in games.
It was simply not feasible for their long term goals (including release time frame and costs) and they said DVD was adequete.
some people just hear what they want to hear.
and the fact that games will be on multiple disc in no way makes that statement invalid.
