They're all gone now.
I wonder if we've seen the last of the physical Vita releases, now. There is one in the Upcoming Releases section of the Limited Run Games website, but it's a visual novel (I really don't care for those). Play-Asia has a listing for preorders of The Binding of Isaac: Rebirth, but other the latest info I can find on it is from back in October.
LRG said their E3 showcase will include the full lineup of their remaining vita games.
No idea for anyone else, though.
