So, today is CP+ show

EXACTLY!

When I finally commited myself to buying a new camera and looked and looked and looked and then finally chose the GRD3 and bought it... well the GRD4 was announced about a week later.  I really liked what I saw (and held and shot) in the GRD3 but was frustrated it didn't have image stabalization.  Fortunately the store I'd bought my GRD3 from was willing to accept a return, so I sent it back to them and then waited and waited and so until, FINALLY, the GRD4 was in stock and I bought it instantly.

So go ahead and buy the GRD4, we're all waiting to see what the 5 will look like!
