Pdesolve will only handle two-dimensional pde's: x,t, or x,y say, not x,y,t.

Only in steady-state.

For time-dependent, spatially 2-D problems you would need to discretize space explicitly and then use an ode solver, like Rkadapt, for the time dependent part. Even this is a drag in MC because the 2-D spatial components need to be contained in a 1-D vector.
