Is UIQ going the way of the dodo?

Here’s a question that needs a decent answer. I know we’ve got a heck of a lot of developers reading here on Mobile Industry Review so I’d welcome your perspective:

Is the UIQ platform still viable for developers to support?

Given that its split between UIQ2 and UIQ3 — there are only 20 devices, with the P800 starting things in 2002. With the upcoming S60 touch interface, will UIQ go the way of the dodo?

Or, is it dead already?
