The problem with Ember right now is the documentation doesn't align with the most recent public version, which will confuse the heck out of newcomers and frustrate people who are still learning Ember. You can however, check out master to get the new router implementation.
I'm personally making the jump to the bleeding edge for two reasons: 1. The old router API is very hard to grasp. A lot of unknowns as far as where domain code fits when building your application using the router. 2. I don't want to be stuck struggling to find documentation for an already difficult API to work with.
With all that said, Ember is worth taking a look at as far as an 'improved' MV* experience, but you have to be careful as it is in a state of flux.
