It's quite possible Nokia won't have their 1st high-end WP devices (at least in the US) until Feb/Mar 2012

They'll prolly have a mid-tier one in several EU countries before the years out, & possibly a high-end'ish one.
But evidence is mounting for nothing in North America until 2012. (some of the user comment are interesting too)
