In my experience, MVC has already become extremely popular among medium-sized orgs with at least somewhat ambitious developers. Very large orgs with rosters of stuck-in-time developers who really love WebForms and custom control libraries, and fear or hate jQuery, well... they're not going to change until MSFT officially proclaims that WebForms are for chumps. Even though they are chumps, that will spur them to change.

I could be wrong, but I don't think that's true. I have come across a lot more ASP.NET MVC + JavaScript jobs than I have WebForms the past couple of years.

I think the shift has quietly occurred because everyone wants at least a little AJAX, and everyone wants jQuery, and once you've thrown those in the mix, who wants to do that using WebForms?

> Point is, there was no huge shift to MVC after it was released.

Why would you assume that if they can't move to a new architecture, they'll move to a new language and OS?

Just the number of unfilled requirements for ASP.NET MVC shows around 2000 openings.
