Although it is a bit bizarre to combine a free sample library with an effects suite, I think people should focus instead on value. This is an extremely fair price for either product on its own. Don't get confused by the unusual marketing gimmick. Just ask yourself if you would pay that amount for either the jazz drums library or the effects suite, and if the answer to either question is yes, then obviously buy the suite now!
Although I own B.F.D. 2 and all of its expansion libraries (including those from third parties), I look forward to Jazz Drums, as I suspect it will be more useful for a genre that's all about expression and nuance. The B.F.D. 2 interface is great, but isn't necessarily ideal for every situation. Vienna Instruments' matrices and control mapping may end up being more appropriate towards a playable and usable jazz drum setup.
