Wii customers aren't willing to pay for the same game four times? I'll bet playing Tiger Woods 08 and 09 is still very popular, and people are happy with it so why upgrade?
The reason to buy yearly editions of "traditional" sports games is to get the new teams, rosters and stats (e.g. Madden). But casual players aren't interested in the professional sport of golf but instead in the enjoyment it provides as a family game. So they don't need updated versions for that.
