One must go...

Just ordered an E-5, should be here in a few days, looking forward to it. Now I'm trying to determine which of my other cameras to get rid of, E-1 or E-3. I could keep both, but don't want/need 3 bodies.

E-3 - can share grip, pretty much interchangeable with E-5 in good conditions.

E-1 - very different from the E-5, that's a plus, but I think once I start using the E-5 I won't touch the E-1 anymore but I will probably regret selling it - been there, done that once before.

Thoughts?
