Here's my theory on this. Universe is going on Hiadus, like it did before. But I'd be very willing to bet that it will be back after TFTM2 runs its course.
This has turned into one of Hasbro's better ideas really. They can include figures from any show they have ever done in an assortment, like they have started doing. thus appleasing Transformers fans everywhere, every age, every demographic.
Want G1, its in the line, want Beast Wars, it is too, Want Cybertron? Ditto for that line.
As to the future I think We'll definitly see G1 repaints for Red Alert, Sunstorm and maybe even Jazz within the universe line. Probably Tigertron and another version of Dinobot too. Excellion for Hot Shot? Probably.
Maybe Movie toys even enter the mix down the road a little.
This is likely the future of Animated toys as well that don't get released now. Brawn as a repaint of Soundwave come to mind as an easy one.
Likely one new mold for each wave topped up with repaints.
I think Hasbro is going to milk this for a long time.
Of course my opinion and 50 cents might buy a donut
