    will top normal der work with 10 speed?

    will the 971 xtr rear derailleurs work with the new 10 speed shifters? I like the new XTR but I am not hip on rapid rise-

    No.
    I just got done talking with the Shimano guys at Interbike, and everything is different.
    You have to redo the entire drivetrain to switch to the new 10 speed stuff.
    To be fair, you have to do the same thing when switching to Sram's XX stuff.
    Shimano says the pricepoints and durability will remain consistent with their current lineup.

    I'm in the "I'll believe it when I see it" group as well. when chains made the jump from 6 - 8 speeds to 9, they got narrower at 9, to accommodate the tighter spacing on the 9spd cassettes. The teeth on rings and cassettes also got narrower, to accommodate the narrower chains, resulting in less contact area between gear teeth and chain rollers (which also got narrower).
    That resulted in faster wear and balky shifting in super dry, or super wet environments.
    Note: that last applies to mountain bikes, road bikes run cleaner and have never been a big problem with more speeds.

    Shimano claims the new 10spd stuff is as reliable as the old 8spd stuff... I'm not convinced until I see it for myself.
    They will at least offer it in a triple, for those that need a more extreme range of gearing.
