I got duped by these guys last year and bought the Wii version of NHL2K9. That thing was an unmitigated disaster and deemed not fun and consequently unplayable.
However, NHL2K10 seems to have addressed a few of these concerns.
This feature preview from IGN highlights a few of the improvements on the Wii version:
- everything in the 360 and PS3 versions is in the Wii version (except the nice graphics): online play, stick lifting, etc.
- motion controls have been scaled back so you're not just flailing around like a ###### when you're trying to play
- Wii Speak
- support for MotionPlus allowing 1:1 motion for shot control, passing and stickhandling
- cursor passing is back and relatively unchanged BUT it's no longer the default passing mode
- graphics have been bumped up and refined running at 60 fps
I think I will rent before buying but it looks like they are at least trying to make things better.
