The minor versions signify hardware changes not introducing any actual new functionality, like redesigning the memory access interface to match the rest of the GPU, etc.
And now status:
VPE v1: already REd, not yet supported
VPE v2: REd and supported by nouveau, though not on all possible cards yet
VP1: early RE work in progress - watch it unfold on the RE blog. Microcode in an unknown ISA involved.
VP2 H.264 bitstream engine: advanced RE work in progress, about 3/4 done. Microcode in 2 different ISAs involved.
VP2 video processing engine: very early RE work in progress, heaps and heaps of work remaining to do. Microcode in 3 different ISAs is involved, 2 of them totally unknown
VP3: RE work in progress, about half done. Microcode in 3 different ISAs involved, 1 of them semi-unknown
VP4: is just VP3 with MPEG4 support, same status
VP5: RE work not started. Seems to be the same design as VP3/VP4, but with the major video processor part replaced by something new
