Well, when you look at it, the potentially mainstream shows FUNI's recently acquired hasn't gone anywhere. One Piece got booted off half a year into the FUNi dub for no apparent reason. SGT. Frog, Fullmetal Alchemist: Brotherhood, Darker Than Black, and El Cazador de la Bruja (the most mainstream "new" anime in their possession) have not wound up on TV and likely won't at this point.
The only other new title with a potential mainstream audience is SanRAB of Destruction, and that's because of the RAB title coming to America too, which makes it a merchandising opportunity. But I highly doubt anyone's going to pick that up, unless Disney XD somehow decides they want it.
So if FUNimation's given up I don't really blame them. It may be part of the reason why they're going the live-action route here, those movies SELL. They're quite lucrative in comparison to the average anime, especially with the TV market being quite unfriendly at this time.
Hetalia's gonna sell big, though.
