If the IQ is anything like the 24-70 2.8 then it could be a nice option from the high priced OEM.

Note this is not a product introduction, it is an announcement that they are developing such a lens.  Similar to when Canon announced the development of the 200-400 w/ 1.4x integrated.  The actual product introduction was much later.

I do agree that if they can maintain the standard set by their 24-70/2.8 then this will be a big hit for them however, since it does not allow any screw on filters it will have somewhat more limited appeal.

I agree the lack of filters could be a draw back but the Nikon 14-24 also has that limitation.

Yes it does and it has dramatically limited it's sales volume to what it would have been.  Note that the Zeiss 15mm f/2.8 solves the problem despite the same bulbous front element.  They threaded the lens shade.

I use filters a lot, mostly polarizers and a 3 stop ND. If that lens doesn't take filters it will be useless for landscapes. Why do they do this?
It will need to be significantly sharper than the EF 4/16-35 to make up for this. Given how good the Canon lens is I doubt they can beat it's optical performance.
