It's been a long, long wait, but Rabi-Ribi is finally on sale for Vita and PS4. There's no CE like originally planned, but there is some separate merch available. Battle Chef Brigade is also being sold for Switch and PS4.
I grabbed a Vita copy of Rabi-Ribi. The bundle of merch is a little tempting, but I decided to pass. Copies of the game already come with a soundtrack, so that's nice. Once again, LRG has price matched a PS4 version of a game but not for its Vita version, which stinks, but I can't complain too much when the Vita version is only $5 extra over the PSN price rather than the usual +$10.
