With the sp3 out is the 10.6" form factor dead? Will there be new accessories for the 10.6 form factor? I seem to remember reading that Microsoft had planned a number of add on items. Then only one I ever saw was the mix cover or will future items all be in the 12" 3:2 ratio? I have had both the sp1 and sp2 and have purchased the dock, both versions of the type and touch keyboards as well as the power cover.
