I bit the bullet and bought Tiger Woods PGA 2010, despite hating real golf. I would have rather got GST but as it doesn't have a WMP bundle I would have had to pay an extra $25 for WMP, so I'll have to pick it up later.
Haven't had a chance to play TW '10 yet but amount of features that the game has sounds impressive. I previously had bought TW '09 and while that had a lot of content I could never really get into it, so i'm hoping that TW '10 will get me hooked. I'm pretty sure that the disk golf will entertain me though even if the main golf game doesn't.
I also preordered Wii Sports Resort so I'll have 2 WMPs.
