Yes, it is always hard to estimate time in any projects. For example, when I first started the VMF exporter, I thought I'd have it done in a few days (at least the basic implementation). As it turned out, one of the main (and primary) functions (getting correct UVW on world geometry) took me almost a year! With help! (In truth, the majority of that function was solved by my friend and fellow WW Andrew Penry ... but the point is that it took a really long time).
Importing SMDs has several problems. First, all models in Source are what you call a Trimesh in Max. That means that once you bring it back into Max it is entirely composed of Tris. That, in itself, is no big deal if you are just reskinning or doing simple things... but it does mean that it isn't as "modelable" as it probably was before it went into Source because it no longer has quads (and cannot utilize many quad-specific functions available to Editable Poly objects).
The normals issue is also problematic because in Max smoothing is primarily controlled by smoothing groups. While you can utilize a Normals modifier ... I have not learned how to integrate that into WW yet. That is a current problem for people who bring models in from Maya to Max with the intent of exporting with WW... Maya normals are stored per face vertex ... and I haven't really figured out how to account for that yet (as the functions I'm using should already work with that based on my understanding but simply don't work). So figuring that out (even for the WW exporter itself) is important... otherwise I would have to try to recreate smoothing groups based off of normals... which really sounds like something that would make my brain melt.
So I'm not saying this will never happen. What I am saying is that it's not something that will get rolled out in the immediate future.
It is more likely that Wunderboy could get an importer working for 2013 before I could since he already has the code to do it. But lately he's been off the radar. I'm sure he's already gotten a horde of emails on the issue... I'm not sure if he's currently taking orders ...
