I still can't see it. Unless SE and Konami have been working secretly on the 360 versions, then I reckon we won't see 360 versions anytime soon.
As Yojimbo stated, MGS4 is out March 2008 and FFXIII will be very late 2008 or early 2009. MGS4 has turned into the game that everyone wants to play. It's been up there as one of the most highly anticipated games for a while now. By the time it's released there could be anywhere from 7-10m PS3 owners worldwide and this will grow as the game sells. Remember MGS3 sold under 4m and if Resistance can sell 1.5-2m so far, then I think MGS4 could sell at least double that over time. Also, this is the last MGS in the series as well.
FFXIII when it's released, could be to a 15-20m PS3 user base and seeing as FF are made every 2/3 years, the end of 2008, beginning of 2009 would be right and a new game, if they make it wouldn't be out until 2011/2012. They would sell well on the PS3 as well.
Both MGS and FF games perform well in Japan (especially FF games), so if it appeared on the 360, they would lose out on 1m-2m sales in Japan. I just don't see the point in making these games for the 360, a machine that currently has under 500k users in Japan after nearly 2 years.
