Here is the Canon RF 14-35mm f/4L IS USM

Size and weight and front filters look amazing....but a few things before I'm ready to swap out my exceptional Sigma 14-24mm f/2.8:

1) Image quality - this thing will need to be outstanding.

2) Flare resistance.

3) How wide is the 14mm?
4) or 1.1) My only concern is vignetting, which affects several recent lenses.
If vignetting disappears at 15-16mm or stopping down to F/8.0, it's an issue only for the inevitable Youtube clickbait.

5) Price in USD and in Eur. We'll see soon.

With the RF 15-35 f/2.8 IS and the 14-35 f/4 IS, I wonder how Canon will slot in a 14mm prime. I hope Canon goes like sigma with a 14mm f/1.8 rather than like its overpriced EF 14mm f/2.8. And hopefully, it'll be designed for minimal coma.
One solution would be to introduce a 13mm prime (on a Friday)

It's clear that ordering the first day (or hour, or minute) is the best way to assure that one get high-demand product in the first batch, usually the first day. Avoids months of waiting for hits like the R5, and the 100-500.

Besides checking in here and elsewhere occasionally, what's the best way to avoid missing out on the announcement of the release, and the oopening up of ordering by retailers? With the R5 there was a live announcement that was the starting gun (and might well have been open for orders prior), but other items might not have a pre-announced announcement time. Any good lists to be on? Frankly, BH ought to have such a thing to tell me the instant it's open for me to buy from them, or in advance.

Never was with Nikon, but the zoom just seems backwards to me. But lenses follow righty-tighty lefty-loosey.

(Yes, that means I too am a PDB.)
When I drive the screw “in” (clockwise) I expect things to be closer. I’m begging anyone for a powerful explanation for the reverse I can use to reprogram my brain.

The numbers on top of the lens go to small to large left to right, just like the way you read left to right. Forget the screw analogy. Heck, forget thinking about rotation direction at all. Just tell your brain that left side of the barrel is small number and right side is large number. By turning the ring you are just moving across a page.
