Also X-box can't make games on the HD Drive, they are forced at the moment to only produce games that the CORE system can handle, thus the normal DVD drive. That's why alot of PS3 Owners are upset with PORTS from the X-box.
In our eye's why should we settle for a less with Sony's promise of Next Gen consoul? We have the cell processer, and a Blu Ray Drive. Tho hopefully we will see these games come out in the next year or two. I am not so unrealistic to realize that these types of games take years to make, even more so to do with the arcitect and new dev kit needed to have and learn to make such games possable. So I am waiting, and hoping.
