Quoted from links:
"SCEJ President confirmed in an interview with Reuters that there is no Monster Hunter 4 for PlayStation Vita unless Capcom changes their mind.
'I don’t know, you will have to ask Capcom,' responded Kawano when questioned if Monster Hunter 4 would make it to PS Vita.
Monster Hunter Portable 3rd has sold almost five million units in Japan only, and it would be a surprising move from Capcom if Monster Hunter 4 did not make land on PS Vita."
I guess Monster Hunter found a new home.
At least this one for now.
