I found this from an interview with George Kamitami, the head of Vanillaware:
 

What do you think are the main challenges to getting to 720p-level of hi-res? Right now, Muramasa is 480 -- how big a leap is it from 480 to 720 -- what KOF accomplishes?

GK: Well, the original art we draw is all done in double-size -- in the case of Muramasa, the animation frames then get compressed down to the Wii's native resolution. As a result, producing a fully HD title would not be a great deal of extra work for us; it would just mean our original art is displayed in higher resolution. It wouldn't be a simple insert -- we retouch the compressed graphics here and there to make sure they look as good as possible -- but it's not restarting from scratch, either.

 With the exception of Muramasa i don't see how any of those games could be remade for 360 and PS3 without the porting cost being superior to the amount it costed to develop those games. They are good games so the more people will be able to access it the better but i just can't see this happen. Also most of the games Marvellous publishes/produces would absolutely tank on anything but the Wii/PSP/DS, I can't imagine the average 360 user enjoying a game like Harvest Moon.

Hmm, that would be good. I want to play this game but It aint worth buying a Wii for :D

" @Linkyshinks: Quite true indeed. The fact that this might be digital distribution makes it sound quite a bit more feasible, i suppose that in that case they would be simply porting the games with no graphical updates since people do not expect everything that is digitally distributed to be shiny unlike retail releases. "

 
 Now Marvelous's president Haruki Nakayama has made a recent blog post indicating that he'd like to bring games to the PS3.

Hmm... if I'm lucky, a 360 port might be announced before the game's European release. I don't mean to bash the Wii, but I honestly gotta say, I think a 360 controller would be a lot more comfortable for a game like this.

The 360 D-pad  or thumbstick, better than a Nintendo D-pad for a game with twitch combat?.  You do know the game on Wii can use a Classic Controller and Gamecube Controller also, don't you?"

If you find the one on wiimote so good then what's the problem? Play with the wiimote. Though there are plenty more games to justify the classic controller purchase if you prefer that style more (brawl, tatsunoko, all the virtual console games, monster hunter 3 etc).

Ah, I didn't know that. Does it really need so many buttons to not be playable with just the remote? It seemed quite simple. Well, I've got a classic controller but I'm not sure I'd choose that yet, it depends on how well the nunchuck's analog stick works with this game. It's nice to play with a detached controller like this so you can do whatever with your arms rather than keep both in a fixed place. I'll probably lean to CC for the d-pad.
