It's quite new, but it's being improved. Sympy will continue to have a separate existence aside from Sage since a) it's BSD licensed so it can be used where Sage can't and b) it can be used completely independently from Sage. As for sympy vs. sympycore, it's my understanding that sympycore is an attempt to speed up the internals of sympy and it may be folded back into sympy at some point in the future. There is also an Axiom fork, FriCAS that is an optional package for Sage. For some things, it is better than the others.
