This news make sense, I suppose Canon is testing (at least) two High Resolution sensors, one with roughtly
100MP and the other with
115MP and this is why, Canon lovers 8K

but 12K is good too

and both resolutions can be used for the first
12K FF mirrorless camera, but once cropped at
1.6X (the "standard" for Canon) it will be a perfect 8K resolution,
DCI-8K(8192p) for a
115MP sensor and
TV-8K(7680p) with a
100MP sensor, both perfect for existing Canon APS-C camera lenses and also the
Super35mm Cinema glasses, this way the wafer used for cutting FF sensors could also be used for a future
R7 APS-C camera, with 39MP or 45MP.
Canon already makes 32.5MP crop cameras, the jump to 39MP is not that big, but 45MP could be also possible, DIGIC X has no problem with the R5 and it will probably be also used in the future R7.
AA filter should and proably will be used, Canon uses the hig-res low pass, it is a four-layer low pass filter that provides 16-point separation available first in the EOS-1D X Mark III and now also in the R5, with the ability of reducing moiré without a huge impacting in resolution.
Canon could use this filter or even something better, other camera maker aren't that much experienced with low pass filters and prefer to do without, at the very high risk of
false colors generated with images containing high frequency patterns.
Canon the only time did without a low pass filter in the 5Dsr also offered the alternative with the 5Ds, there is no need to avoid the AA filter once you have 120MP or 100MP there is already plenty of resolution, the advantages of having a good AA are much more than the disadvantages. moreover, while undocumented, I think a camera without a good low pass filter will negatively impact the capabilities of Canon
dual or quad pixel AF, as false colors could potentially mislead the AF algorithms.
