Until Maya 2014! (The trial at least )
Apparently there's an 'Accelerated Modeling Workflow' feature. Whatever that means, all I'm saying is that it better be good, you bastards! Interactive Split Poly tool was not a good addition to the modeling toolset.
Go here to see a floating head frown a lot and talk a lot.
Here's a video of the advanced modeling workflow stuff in action. It reminds me of the NEX tool set. We'll see how it works when I get my hands on it :D
