I actually really liked the first PoP for the Wii ( the one that was ported from the GC and PS2 but had enhanced Wii motion controls ).
Call it a gimmick, but I enjoyed swinging my left arm to grapple on the walls Metroid style.
The story was very good too.
So I'm looking forward to this one, if they kept the same gameplay ( which I was perfectly happy with ) and slightly updated the graphic ( honestly the previous one was badly ported ) at least so that it takes full advantage of the Wii capabilities, then there would be nothing else to wish for.
