Mario Advance 4 slips
Oh brother.
Super Mario Advance 4: Super Mario Bros. 3 has slipped, apparently, due to Nintendo's inability to fit the entire name on existing GBA packaging. Or, perhaps more accurately, because it needs more time to finish dusting off the old Mario All-Stars reworking of the seminal NES platformer for localisation and eReader-related reasons. That's IGN's hypothesis anyway. The resultant slippage in the US has seen SMA4 tumble from September 22nd to October 21st. Whether it'll do similar over here remains to be seen.
