GameSpot reports today that Castlevania: Symphony of the Night will be the first Xbox Live Arcade title to break the 50 MB size limit (we were wondering how the hell they got the voice acting and audio in there). The limit was imposed so that 360 owners could transfer Arcade games to memory card, allowing them to be played on another 360. Xbox Live's Greg Canessa told GameSpot that the cap is still in effect, but Microsoft can and will make certain exceptions. Citing SOTN as one of the "most popular games of all time," Cannessa felt that an exception was in order.
We've blogged about the 50 MB limit before, and it will be interesting to see how (and if) Castlevania will affect future developments on Live Arcade.
Update: It looks like GameSpot got the trial version info wrong. MS informed us (and GameSpot) that it will not fit on a standard memory card.
