I'm waiting to see what is possibly in the up and coming pipeline as I cannot decide for the life of me whether to bite the bullet and go for the EOS R now or wait for the inevitable EOS R mk 2 with, hopefully, IBIS - which for me is important - and possibly other advantages. I don't currently have a huge arsenal of Canon EF lenses, L or otherwise, so I don't need to really get too concerned with respect to replacing them with current or upcoming R lenses. Using the EOS R lens adaptor does not fill me with excitement - it's yet another bit of kit to have to keep with me but I can see the advantages for those who have already invested heavily in the top end Canon EF lenses. My current body is the 1DX which is starting to look a little lacking overall and is big/heavy to boot however the AF and FPS suit me well and I've managed to get some images that a lesser body might have missed. The 1DX mk II does little to excite me at the current price but the EOS R is tempting but not yet totally convincing.
If I do 'upgrade' I'm inclined to keep my 1DX as resale value isn't great but is the EOS 5d mkiv a better option than the current EOS R as an additional body?
I'm not a professional photographer; interests are generally landscape, birds, flora and fauna.
Input/thoughts would be appreciated.

Rah. As with you Bob, I'm not a professional, but I do have money invested in camera gear. Going mirrorless makes no sense for me at this time or probably in the next five years. I purchased my 5DMkIV this last spring and wasn't the least upset when Canon came out with the R.
Now if you have seen her work, and it is quite good, or she is published or her results have been published in some way or another, then that adds credence to her assessment. I don't know her, but I do know what MANY have stated as their own experiences across the forums and video reviews from known individuals, and her account is contradictory to others.
