<p><a href="https://www.canonnews.com/canon-patent-application-10mm-28-aps-c-br-and-35mm-14-br">Canon News</a> has found a BR related patent application (Japan Patent Application 2018-54914) that deals with a variant of the 35mm lens, but interestingly enough also contains a 10mm APS-C patent embodiment.</p>
<p>We’re obviously not getting a new EF 35mm f/1.4L lens, but the EF-S 10mm f/2.8 prime is interesting. People have wanted a wide angle prime for APS-C for as long as I can remember, but I’m not sure we’ll ever see such a lens come to market.</p>

I'll get the EF-S 10mm f/2.8 lens if it ever gets released!

Might these lenses be Ef-m mount lenses? I really hope so. Ef-m 32mm F 1.4 is already confirmed, so why not?

How about a 28mm 1.4L BR 8)
 
As someone that shoots bmx videos, this would be incredible! I use my 10-18mm daily, so extra f-stops would be such a huge help! Too bad they can't make this in a zoom. 10-22 2.8? DREAM.

Also, first post, long time lurker! :D

The backfocus distance would likeny indicate if that is the case.

There is a really nice (and fast) Tokina lens you might want to look at...... I’ve got the older version which is 11-16 at F2.8, but I think the new one is 11-20 at F2.8....

What does BR stand for?
I'm not sure if the person above me is being serious, but:

BR = blue spectrum refractive
