TM is now open source and a lot of ST users are stuck at V2. I dont think there is a lot of room for another product.
I don't know that I'd say Sublime users are "stuck". The long beta on v3 seems to be splitting the community, somewhat, but it wouldn't be surprising if the final release resulted in it consolidating again.
I've already movers most of my we stuff to IntelliJ/WebStorm. I really liked ST2 but was a little miffed that right after I bought my licence ST3 was pushed to the forefront of the site without a reasonable upgrade plan.
