I own an EOS R5 and I do mainly landscape and astro (Milky Way and so on....).
I use the RF 15-35 f2,8 with the MSM rotator star tracker but indeed a faster/brighter lens would be a bonus.

In my photography sometimes I also would like to use a wider fish-eye lens, for dramatic images so now my major question is what would be the most obvious choice: the RF 14mm f1.4 or the RF 7-14 f2.8 considering the fact that I have already the RF 15-35 f2,8? In terms of wider images, is the new RF 14mm f/1.4 making the images much wider compared to the RF 15-35 f2,8? The faster lens is of course handy BUT at the end it is a bit more important to me to use a wider lens rather than a brighter lens, since astro is NOT my only photo genre????

That depends on how much Canon wants to charge for it. The 21MP Canon 5d2 made the 21MP 1ds3 virtually unsellable. The 24MP Nikon D3X was replaced after 4 years by the D800, with 50% more pixels, a less rugged body and a 60% price reduction. People who want lots of pixels don't seem willing to pay for extreme ruggedness

Indeed that’s what history tells us so far. I’d see an ultra high mp R3ii as basically a ‘R5S’ configuration.
