Sleep on it for a while... Plenty have fallen in and out of love with the XP1 and you only just got that one
The XT1 is (give or take) quite near the bottom of it's depreciation curve, so no rush
The XT20 is probably at the prime time in its life for being an expensive mistake if you flip it (but someone else's bargain)
If I had to chose for you, I'd keep the XP1 and XT20, that's sort of the best of old and new Fuji X worlds IMO
I agree and is what I'm thinking. For now I'll sleep on it. Let me say that I love all in a different way.
