I suspect that given time, they will become rolled into the CC.
It's not a smart pricing plan and I doubt it will play out well. When Adobe has a bunch of touch apps no one's buying, they will roll them into CC. I mean, who else besides CC customers would be buying them?
This is the same thing that happened when Adobe insisted on having corporate pricing for the Digital Publishing Suite when everyone using it was asking for individual plans. Low and behold, that plan is now slated to be lumped into CC.
And I know that once I pay for CC, I am not ponying up money for anything extra. I'd rather do without.
