Xbox LIVE’s Director of Programming Larry Hryb, better known as Major Nelson, has confirmed there will be no new Arcade releases this week. The games that were supposed to be released this week were reportedly Sega’s Rez HD and Ubisoft’s Chessmaster Live.

Undertow, the free game that Microsoft is giving to all members to compensate for the Xbox LIVE issues, will still be available as promised. You can download the underwater shooter tomorrow, starting at 2:00 a.m. PST and it will remain available until this Sunday, 11:59 p.m. PST.
