yeah I added the 10-22 that I missed out and you will notice the 3 lenses are they 3 that preserve the wide end on APS-C they are they only EF-S lenses that fit into the higher quality bracket. for the tele end APS-C give you the 2 added benefits on the EF lenses of sweet spot effect and the additional reach.
If the 70D steps back into having decent build quality and good features and regain the top level APS-C crown
it leaves room for a high performance APS-H camera which has the following significant advantages over APS-C
1) significantly better image quality
2) still get the sweet spot effect
3) till get some additional crop factor reach but not at the expense of image quality
4) ability to increase FPS over FF
of course this is all based on current sensor tech, If crop sensors can overcome the current IQ issues and approach current FF IQ then I would expect to see a similar jump in corresponding FF image quality.
Personally I think the way to go would be for a APS-H camera to enable a crop mode similar to nikon with EF-S lenses giving a boosted FPS due to smaller file sizes
for example 8 FPS in APS-H mode and with an EF-S ens attached the image size is reduced automatically to fit the image circle and FPS increase to 10 FPS
Also important would be to not use the new 61pt AF and use the old 1D 45 pt AF including the f8 AF
this would be the best way to make a killer crop camera that can really hand it to the competition but more importantly fill several gaps appearing in canons line.
I still maintain there are only 3 EF-S lenses made by canon worth owning
