I'm just saying, there's no record for success on HD consoles for subscription based online RPGs. DCUO flopped hard and went f2p, FFXI 360 barely made an impact (subscriber base there is still mostly PC) and ditto for Monster Hunter Frontier and PS Universe. There's actually a better record for success on PS2/Wii than there is PS3/360 for this sort of thing (FFXI, DQX, MH1-3, PSU, etc).
For DQX as well, I think redesigning the game with a f2p option is the only way it'll see wider reasonable success in the west. Porting the game as is to PS3 or 360 (Wii level assets, subscription model) would result in it bombing just as hard anyway. If SE wants to aim wider, that should be their priority (f2p conversion, PC port, then maybe other consoles). If SE wants to stay with a small dedicated subscriber base in the west though and leave the game as is, a Nintendo incentivised deal might jot be a bad route either. Less potential return, but less risk/investment too.
