This question is asked completely wrong. The real question is...
Do you think the PS Move is worthy of one of the best action games made with motion support?
I played No more Heroes on Wii and let me tell you its a blast. Like most wii games there are limitations and somethings come off better then others, but if you own a PS Move, you have never played No More Heroes before and consider yourself a Hardcore or action gamer then there is no question as to rather it is worth it.
No More Heroes has some of the best dialogue and boss fights I have ever seen. Its entertaining and not afraid to embrace its campyness.
Assuming that the controls work as good as the Wii controls do and the port is done well then this is a no brainer.
I know the Move can do Wii motions easily but that doesn't mean the development studio will do a good job just a FYI. Getting the controls down is going to be the key component to making this title worth it.
