Monster Hunter Vita was never a real thing. We've had plenty of time now and no information has emerged whatsoever to suggest that it ever existed in even the earliest stages. It never made sense to exist, the 3DS was a significantly better platform choice (and Capcom were never going to take the series multiplat and thereby screw up local multi.) It wasn't a moneyhat.
I'm not even arguing with your position but that's the same bad rhetorics you've used in the past on Tales for example. You shouldn't state something as a fact that you can't prove, however plausible it may appear.
