Yes, MVC3 the way forward. I've spent the last year pulling together my minimum viable product with MVC and choosing ASP MVC 3 has to be the best decision I've made.

My only negative comment about ASP MVC is that WebForms requires very little code to create a sexy interactive expanding/collapsing databound table whereas you seem to have to write a lot of code to do the equivalent in ASP MVC (v3 at least...) There are however some great libraries out there like jQuery MVC Grid (http://jqmvcgrid.codeplex.com/) which fill in these gaps. With the current speed of development, it is surely only a matter of time before WebForms becomes obsolete.
