Not sure if this is worldwide or only for PAL regions (Europe / Australia / NZ), but it's on the list.
If you have PS Plus membership, "buy" a copy even if you don't have a Vita, if you think there's any chance you might ever get one. You can save it and then download it later if/when you do get one.
Yeah it is Worldwide, it's showing up on the NA lineup aswell.
Already bought the game anyway as it's only £7.99 normally anyway.
Yeah, I bought it too when I first got my Vita. But on the offchance there's anyone here who has (or is planning to get) a Vita but doesn't have Lemmings Touch yet, I thought I'd mention it.
