Okay, even if the comments by John Carmack are a bit overstated, the idea (or prevailing notion) seems to be the PS3 is more difficult to program for. Combine this with the news post from a couple of days ago about the EA Fight Night 3 footate, http://www.totalvideogames.com/news/EA_Promise_Fight_Night_3_Xbox360/PS3_Identical_8186_5020_0.htm
, (not to mention the rumored higher price) and it looks as if the PS3 may have more of an uphill battle in the next gen console wars than Sony expects.
The Sega Saturn had similar problems during it's time. Even thou it was the best platform at release, it was considered difficult to program for. And, it was more expensive than anything else on the market. Seeing how that situation turned out for Sega, especially considering it was Sony (Playstation) that profited from Sega's mistakes, you would think they wouldn't be willing to make similar ones. Then again, the view from the "top" is always a bit different.
Even if the PS3 has more horsepower, if publishers like EA are willing to develop for the lowest common denominator console, that extra PS3 power may not be needed. If true, then titles purchased by Average Joe/mass market gamers (i.e. the majority of the market) will not reflect the "need" for the extra expense of the PS3.
Ah console wars are always interesting times... :}
