Not to be cynical, but it sounds to me like a revamped marketing strategy more than anything else. The sport category you're excited about sounds great, but have they improved their AF speed?
According to the info on the new 120-300 one of the things they changed was AF Speed as well as adding a focus limiter and some form of control for the focus speed...
While its obviously a lot of marketing, I think its good marketing, Its designed to grab consumers and say "Megapixels are NOT what matter, Cameras DONT matter, Lenses MATTER" and reorganizing things to be a lot easier for your average consumer to sort of understand....
As for zooms in the sports category, the 70-200 f/2.8 is a very popular lens for some sports, Personally I think zooms are VERY useful, but i expect a big fast tele is on its way... With recent price increased
My guess here is Sigma is going to be dumping a lot of the old models, Some lenses just simply arent needed/dont sell much right now, I expect them to be discontinued, Probubly some of the old primes like the 20mm f/1.8, 24 f/1.8 and 28mm f/1.8 will get the sack, but id also expect to see some replacements for some lenses, Sigma could use a fast 24mm lens to go with the other FF fast primes for instance..
I expect more recent lenses will get a facelift, See the 85mm f/1.4 and 50mm f/1.4, Also the 70-200 f/2.8 OS as well, I wouldnt doubt a tweak or two to the internals on these lenses happening either...
The 105, 150 and 180 OS macros will get facelifted, All three are brand new, I expect, and want to see, a 50mm-class macro with HSM and OS as well, Bonus points if its f/2! 
-edit- nevermind, reading descriptions answers my stupid question
