Canon to release an RF 5.2mm f/2.8L next?

Maybe typo (or something lost in translation) ?
Wouldn't it be too short even for a "normal" circular 180° fisheye on fullframe?
(Though there are several variations of optical projections/corrections)

It seems that Canon is definitively signaling that they are going the full hog in the RF system. I wonder what other surprises are coming.

This makes total sense: Shooting streeview half spheres with one shot you need more than 180°.
Those Googles, ... do it today with multiple camera arrays. One single shot with a 45MPX sensor facing the zenith can do the job.
Every of those Google, Garmin, Apple, ... cars/rigs bings back terabyte of data day by day to be spherical stitched.
You probably can heat towns withe the power wasted for processing.
This is a professional market worth to be targeted.
This market is selling by far better than i.e. tilt/shift or things like this.

A lens for this use case can cost the price of a car and will be sold.

I'm thinking of the Nikkor 6mm f/2.8, which has 220° field of view, and it's huge and costs a fortune.
A 5.2/2.8 one would be humongous, even if Canon pulls some serious optical magic out of their hat to make one.

I'd definitely love to see such a thing, even if I'd be very unlikely to buy one.

An APS-C circular fisheye (Canon's APS-C sensors have a crop factor of 1.6x)? That's why the special, dedicated cap?

I thought about that too. Maybe if it's a fisheye zoom that GOES to 5.2 (passing through 8 on the way), it could be setting up for use on an eventual APS-C RF-mount body? If it's prime 5.2 it would leave a lot of the sensor unused on their entire RF line to date.

What is the reason, you didn't think that before?
What was the last EF "signal" ?
I did think they were serious about RF all along. However, until now, the RF lenses they produced tended to reflect the EF lines, albeit with additional features and performance matching or exceeding the EF counterparts. The 5.2 is a significant difference, and hence a strong signal/affirmation of their claim to have a strong RF focus.
