You're using all 3, you tell us maybe. Does the XT3 have enough over the T2 for you personally? It wouldn't for me, I'm not fussed over speedier AF - I had the XT1 for a couple year and never really found it too slow for my needs, well, maybe a little when coupled with a slow lens like the 35 1.4. The XT2 is that good the T3 had to boast extra video features to make the upgrade worth it for many. If you really want the H1, I'd ship the T1 and T3, keep the T2 - same sensor as the H1 so your processing will match up for both.
