1UP has put on their site an article by Dean Takahashi, author of Opening the Xbox and other recent articles about the successor to Microsoft's Xbox gaming console. This article originally appeared in print for Gaming Industry News and was subsequently Slashdotted. The focus of the article is whether or not the new Xbox will be compatible with the old; he asks representatives from both Nvidia and ATI and gets conflicting answers.
In the end analysis, Takahashi seems to believe that backwards compatibility greatly benefited the PlayStation 2, a sentiment I happen to share despite it being downplayed by some in the community.
