Will the cost of online play affect your purchase of Monster Hunter 3?

As long as I don't have to continually pay I don't think i'll mind... I would probably only pay for 1-2 months worth.

Unless of course there is no way to play the game single player? as in that case I don't think i'd buy it.

It is free to play the game on single player.

Question:Will this game support duels like in Diablo II LoD or will online just be Co-Op like Fable II?
