[Update: Ravidrath of Lab Zero Games has added a bit of clarification to the situation.]
Last night on the Salty Cupcakes 'cast, Skullgirls lead Mike Z dropped a bomb on the fighting game community -- their console publisher, Konami, wants Skullgirls to be removed from the PSN and Xbox Live Arcade almost immediately (December 17th for PSN and 31st for XBLA). This came as a shock to Mike Z and the team, who basically had no idea this was coming. In response, developer Lab Zero is planning on making a brand new build for consoles with Squigly in tow, under a new publisher, Autumn Games.
The Japanese release isn't affected (as it's handled by CyberFront), but it is entirely possible that Skullgirls will disappear entirely on consoles in other regions until sometime in 2014. For now, it appears as if the PC version published by Marvelous AQL is completely stable, but I hope that the team lands on their feet, and can get a new console version up as soon as possible.
For clarification, if you already own Skullgirls, you can still play it even if Lab Zero isn't able to solve the problem. Support for online play however, is up in the air at this time, and non-owners will not be able to buy the game after those dates.
