That seems to be the plan, yes. Ivy Bridge is already in tablets, but battery life is not as good as something like Clover Trail.
Haswell has a lot of delicious power gating/saving techniques that will make tablets a LOT more viable with the 10W version of the chip, but I think at 14nm is where we see an iPad-style tablet with a "Core" chip.
Basically, the "Atom" line becomes the "Celeron" of tablets.
