Might want to look at it another way! If you stock up on some, you probably would have bought them anyway, spending current cost (if they weren't going away) . If they go on sale, oh well you're no worse off. But no matter what they throw at us, you're just prolonging the inevitable, going to have to get the new ones eventually.
Me, Im going to stock up some, let all those that dont, experiment with the new and I'll learn from them. Collect their expertise, and be the better off, for it. That's how I learned which balls and clubs, to go with, up to this point!
