And SLX. I find that Shimano made a very good decision when going 10s with XT and SLX. In 2011 10s isn't just for racers or people with thick wallet.
I presume that XT and SLX will be pretty reasonably priced when compared to XX, X0 and XTR and that's a good thing for customers who are willing to try 10s.
I'll definately buy XT RD, RH-shifter and 11-36 cassette when they are available and use them with my 40t XTR-960 crankset, DA7900 chain and MRP 1.X chain guide

. Should be pretty light setup with good gears and not too expensive
