High quality photos is meaningless. What photo subjects are you interested in? Different cameras may have different functions that are more suitable to specific applications, for example different AF capabilities, different bracketing capabilities, and so and so forth.Not concerned about budget.
Don't care so much about the number of functions.
I just want the highest quality photos.
Or should I wait for the next OM-D to come out?
I presently have 12-40mm PRO with my E-PM2.
The best choice from what I can surmise from your information is the Olympus OMD EM1.The first criteria I consider is: do I need an EVF of not? Don't need, perfectly fine with screen.
Is weather-proofing a must have? Yes, -40C here in Quebec, Canada, love to capture the festivals here. And I don't like to postpone photoshoots in the rain because my lens is weatherproof but my body isn't.
Or is the smallest size? As long as it's not those DSLR monsters.
Do I shoot a LOT of sports where the EM-1 AF could be a little better? I shoot boxers, so punching and stuff, a lot of action.
Do I need 1/8000s shutter speed? Do I?
Am I going to use wi-fi more than once in a year? Yes, absolutely.
Do I want the most comfortable grip? E-PM2 thumb grip isn't the best.
Do I need "live bulb" for night photography? Yes, I like making those light trail pictures.
What camera suits me?
I also want Auto ISO.
