Yesterday morning, 150 souls got aboard flight 4U9525 of German Wings to get to their destination. I'm more than sure that they had plans for today but, today never came for them. Maybe i sound tragic but, nobody knows if tomorrow ever comes; if you want it and you can do it, do it...YESTERDAY! So, i'd friendly suggest you, not to wait for any tomorrow and what better (?) it should bring to the table, go ahead and do it NOW!
And a few more words; i own both 5D Mk3 and 7D mk2 and as i can see from others, once Canon jumped on Dual Pixel AF wagon, although quality of focusing during video is really excellent, focusing during shooting photos has clearly declined. That generally happens to my 7D Mk2 too, with some (3rd party usually) lenses, with aperture faster than f/2.8 (mostly). There are lots of reports for 70D too, which also uses the DPAF system. Being absolutely sure that 5D Mk4 or whatever the successor of Mk3 is, will implement DPAF system (especially after Canon having released EF 24-105 IS STM) will "suffer" the same issue. As an engineer, i strongly believe that DPAF has a bunch of pros and a few annoying cons, single point AF being one of them.
That's my 2 cents, do what you think is best but, remember life is too short to wait forever.
Always be lucky, be healthy and strong, live your life with those you love.

Yiannis.
Dpaf is only used in live view. It is not used during regular af.
Dear candc,
I know that DPAF is only used during live view but, i find it relevant that the only 2 models that use it in present time, both suffer (many people don't even know it but, their own camera has the "bug" from f/2.8 upwards) from what seems to be the "center point AF issue". As an engineer, i suspect (maybe it's only my BS thinkink) that, DPAF and the way the CMOS/mirror box/AF sensor are constructed or assembled to work individually or together, reproduces the issue. Again, maybe it's only my conspiracy theory but, don't forget that, it took a long time to canon to present 7D Mk2 "due to AF issues".
Be lucky, be well.
Yours
Yiannis.
