I prefer solo and have a buddy on board to play 3G, so I don't care that much. Still, I was hoping for online play since it would mean better localization chances / better sales in the West.

Obviously, Capcom didn't think it was worth the cost of coding netplay and running servers when everyone plays adhoc. Since MH4 is a portable game too there might not be a new online Monster Hunter ever again.
