I won't pretend to know much about the business side of this, but I will be very interested to see what this means for TM going forward in the equipment market. I think most of us realized years ago that what TM was doing with new product intros so often wasn't sustainable; painting drivers white, then with stripes, then back to black isn't a long-term strategy for products that cost big dollars.
I don't think it is luck that Callaway has made progress; I read an article several years ago about their then-new CEO, who junked the stuff that was in the pipeline when he came on board and has put Callaway on a product cycle more like Titleist and Ping than what Callaway and TM were doing at that time.
By contrast, a couple of weeks ago TM announced a program where golfers could, in effect, lease TM clubs so that they could get the newest stuff immediately and just keep paying their monthly fee, much like a cell phone purchase plan model. It struck me as desperation when I read it, and still does.
