Why is "Multiple Displays" still only "working very hard in this direction"

Dear Parallels Team:

I would like to remind you that you have responded multiple times to requests for true multiple display support with assurances that "we are working very hard in this direction". These types of messages have occurred over the span of the last year, and I for one fell that you've not been honest. Apple can release a new OS in the time it takes you to build a feature it seams.

I think you owe your users an honest, realistic estimate of when if ever we should expect to see this...
