By choice.
Just as some buy new computers, phone or cars every year as well.
Most don't buy a new car every year, but they still update car models every year. Because even if the guy that has a 1 year old driver won't buy one this year, some other guy with a 4 year old might want one. Sure, some buy "it" every year, but not most. If an 05 3 series was 100% the same as the 09 there's less incentive to buy new and more to buy used.
Golf equipment generally has good size markups because they aren't a high volume sales item. Every Sports Authority I've ever been too has oodles of TM drivers and woods. Not so much other brands. There's this year's stuff with the big markup, like a R11 for $300, and last year's Burner for $129. My point is, Taylor Made and to a less extent Nike are more stocked at the big retailers like Dicks and Sports Authority then say Srixon or Titleist are. The bigger stores are more able to carry excess volume and sell "last years" with a small markup, while the more money the company has the more stock it can produce and sit on some of it's own inventory to sell last years stuff at cost.
I would love to know how much Dicks and SA sell compared to the rest of the retailers, but I'd be shocked if those weren't the two biggest sellers of golf clubs in the country. And TM and Nike are sure up in their stores more then the other brands.
