Both C30 and C32 are GCC based, though I don't know if they keep to the
same revision (of GCC). The changes are pretty incremental in the step to
the XC compilers, at least initially. They're not a whole new set of
compilers. The first step is branding and trying to remove the existing
confusion with the compilers and naming conventions. What's there will
remain there, and initially, I think the convention is just a naming
convention (Hitech PICC and PICC18 become XC8, though I believe with a
flag to compile C18 syntax), all the different flavors of C30 become XC16,
C32 becomes XC32.

In the long term, I believe it is to go with the general philosophy of
MPLAB- one IDE across all the architectures, similar register naming
conventions- in that spirit, trying to make the syntax of the compilers as
similar as possible.  A welcome change, as I think anyone who works across
Microchip architectures and compilers will agree.
