To help prepare for some new features in the future, XBox Live is going to be down, possibly for all of Tuesday, to perform scheduled maintenance. Great games on Xbox LIVE and Xbox LIVE Arcade: Xbox LIVE Arcade is keeping the fun rolling all summer long. We are continuing our commitment to quality and innovation by delivering five weeks of downloadable blockbusters with the second annual Summer of Arcade — bringing you the biggest and best smash hits of the season including Shadow Complex, Trials HD, Splosion Man, Teenage Mutant Ninja Turtles: Turtles in Time Re-Shelled, and MARVEL VS. CAPCOM 2.
Last year Microsoft also ran their Summer of Arcade for five weeks, from July 30 - Sept. 2.
Seeing that this year is also five games that are scheduled to be released over a five week period, and considering the current calendar has nothing listed in regards for any of these games for the month of June, Microsoft mirroring what they did last year is looking more and more likely.
So it's not much of a stretch to assume we'll be seeing a Marvel vs. Capcom 2 re-release some time in August.
