New Xbox Experience launch. The origins of this version stem from The Inquirer ("Sony, Microsoft begin battle of virtual worlds"). It's also interesting to note that the article does not mention NXE's simultaneous launch date.
When you search the AP website, however, you will instead come across a "Sony, Microsoft virtual communities to start" from the same day (via Yahoo!). In this version, Home is "dated" for "later this year," while NXE is coming November 19. Both pieces also use the exact same quotes from Enterbrain's Hirokazu Hamamura, Sony's Ryoji Akagawa and Microsoft's John Schappert. It's likely that the former piece was an earlier, now-corrected draft from the AP or a gross misread by The Inquirer (and subsequently propagated from there).
It should also be noted that at Sony's Tokyo Game Show press conference this weekend, the company announced an open beta for Home would be launching in Japan this month and end in November. We've gone ahead and contacted Sony and AP to confirm.
