Monster Hunter is taking up a large chunk of the rumor mill today. First off a rumor from Japanese magazine Gamelab stating that Monster Hunter 4 would be released simultaneously on Nintendo 3DS and Playstation Vita, apparently the cause for it’s delay. That particular rumor has now been debunked by Capcom however, with Capcom Senior Vice-P Christian Svensson saying “I would not believe everything you read on the internet. It will set you up for disappointment or misdirected frustration.”
Another rumor has popped up, that could possibly explain the reason for this. Coming from a source with a good track record, having previously leaked the arrival of Monster Hunter 3 on 3DS. In a post on the gaming section of the TGFC Club message board from 2011, this same user seemingly called the Dragon Quest VII remake for 3DS a full year before it was announced. In that same post they talk about a deal between Nintendo and Capcom which would see handheld Monster Hunter games coming exclusively to the 3DS for the next three years.
Capcom is yet to comment on this rumor.
