User blog comment:Kogath/Monster Hunter 4 Ultimate for the Nintendo 3DS/@comment-184612-20140311192826

"The Ultimate name naturally brought some to consider the dual release of 3 Ultimate on the Wii U and 3DS — the sequel is only confirmed for the portable, however. While acknowledging that the name Monster Hunter 4 U would have a charming ring to it, Tsujimoto-san made it clear that the team is only focused on the 3DS at this time. Yeah, that title naming would be a lovely coincidence. That would be pretty sweet. At the moment we're focused on 3DS, purely because with the previous title, the 3DS version couldn't go online on their own. There was a system to bring them online in conjunction with the Wii U console, but they were only local wireless play by themselves. In 4 Ultimate, it will be online play just on the 3DS. We really want to see how having just a single platform online multiplayer game works out. So at this time we're focusing on the 3DS version. Monster Hunter 4 in Japan was also 3DS only."
