I dunno.. I kind of see it as the opposite approach.
I think while this thread full of geeks focuses on the Pro version, MS's marketing and sales will focus on pushing Windows RT. I think they see the "Pro" model as selling only moderately well, but to people who need it more as a tool, so are willing to spend more... whereas the market for the RT version is the real big money maker, sell 10 million devices, etc..
And that market is used to buying 1.99 software and then complaining in reviews that it wasn't 99 cents.
And they will keep trying to push Metro UI on their desktop developer partners.
