I'm planning to purchase an X-E3 or X-E2 (perhaps used) within the next several months. So far the best deal I've seen is a used X-E3 for $649.99 CAD ($508.39 USD). Does it make sense to buy it now, or to wait for a price drop when the X-E4 is released?
And is there a big difference between the X-E2 and X-E3?
