I went all in with mirrorless, selling my dslr's when the R3 came out and was waiting for an R1 for a long time. Everyone was kind of expecting something more from it, myself included. I just wish it had a 32-35 mp sensor and MAYBE a global shutter, but it really does seem like the R5 has everything the R1 does and a little more. The only thing stopping me from getting the R5 is the smaller body, no touch AF controller, the overheating (even with the battery grip vent), and the LP E6 Batteries (they just aren't that good compared to LP E19's). I also used the original R5 and returned it after a few weeks because it kind of fell short. I do a lot of weddings, more video than photos sometimes, so the video features are nice, but the R1 would have been my main shooter for both photo and video but again, it just feels like a R3 update. Getting the R5, plus the vent grip, PLUS 8 BATTERIES (all the old LP E6's wont be as good) it would be $1,000 less than the R1 too. Money isn't the issue for since it's for work, but dude I really agree with the sentiment that it doesn't FEEL like a flagship body, especially when compared to Sony or Nikon. I already have my pre order for the R1 in since last night, but I've never second guessed myself on camera gear ever. Maybe someone here can help me make up my mind.

Edit: thanks to those who were helpful, not so much to those who weren’t. Cancelled my r1 order in favor of the r5. Losing some nice photo features in favor of video features. It is what it is.
