Code size was never the limit. Things that take up the most space are pre-recorded high-definition cutscenes and uncompressed sound, both of which are just desirable add-ons, even for games with a focus on presentation. Wii, DS and even PSP games prove that that the best games are not necessarily the best looking, and indeed the massive budgets needed to create such content are often never regained with less than what is considered stellar sales. It is not worth the additional cost at this point - this is why I believe Microsoft did not include HD-DVD when they had the opportunity.
Ubuntu. Linux for human beings.
