I just changed my mode to cRAW. I'll try it for a while and if I do not notice a difference, it'll be here to stay.

The first issue appears fixed. I've heard reports that the start up time is much faster, and the weather sealing is better, but those are somewhat TBD. The animal eye detect I am curious about myself. There is a lot of emphasis on sports, particularly with the R1. But not much chatter about animals, at least not that I've heard. As for the single-point square, I use the smaller point. Historically (5D III/IV) the smaller point was slower and I used expanded point AF. With the R5, I use the smaller point and it works very well for me.

I still have a few days of thinking before I decide if I will cancel my pre-order. Overall, I preach "shoot to need" and I do not have many needs with the R5. However, it does look like the R5 II fixed my minor quibbles and I do like my gear . So the temptation is there.
