I see 69 bugs WONTFIX'ed in 5.0-final on up and 17 bugs already lost to Fremantle, being FIXED in Harmattan instead, but a whopping 157 bugs FIXED in 5.0+. We know there's at least a 1.2 update on the way for Fremantle, and there's been hints of other, additional updates beyond that, so we're not at that Diablo-like "Yeah, we fixed it internally, but we're not releasing it" stage.

To say I'll be unhappy if Nokia does not make Harmattan available for the N900 is an understatement, I assure you. At the same time, you're exaggerating a wee bit here about how bugs are being resolved.

EDIT: As GeneralAntilles points out below, I didn't take into account where bugs were filed, so my Harmattan count is high. Many of its bugs were introduced with it, not Fremantle. In short, GA's numbers are better.
