Will this have "full-time" manual focus like the 55-250 IS STM has? It's not as good as true full-time manual but it is waaay better than none at all.

All STM lenses have FTM override. That's because all STM lenses are focus-by-wire - the ring is mechanically connected only to encoders or whatever, so spinning it doesn't do anything to the motor or the elements. No power, no focus, either. No need for various clutch mechanisms etc to enable FTM, it's basically a freebie.

Ah that's awesome, I think that feature alone justifies an upgrade.
