In its latest developer diary, Microsoft's Gamerscore Blog highlights the NXE Community Games Channel, which we've heard about since February 2008. The separate channel will let theoretically anyone who submits a game and passes peer review to sell their title to other Xbox 360 owners (with Microsoft, unsurprisingly, taking a little bit off the top).
What is surprising to us is that the peer review process there's only 48 hours between the time of submission and release on the channel, a much shorter time frame than Microsoft's weeks-long certification process for Xbox Live Arcade games and title updates. Video embedded after the break; the New Xbox Experience launches November 19.
