I noticed a detail that no one seemed to talk about:
It has no symbol for online multiplayer, so the version would be rather pointless.
I don't think it was a PEGI error, that would be very weird. It was probably removed because Microsoft or Nintendo asked for it.
The release date on the PEGI website means that a game is allowed to be released. It's sometimes months before the actual release. The non-existing Vita games were probably initially planned and cancelled.
