Ah LO, 'tis the same ole me. Sorry.
I speak as I find, where I can, and views are always my own.
Though the USAF is gunning (excuse pun) for a new Warthog, the F-35 has already conducted CAS trials in OT and by the Line squadrons alike, and performed remarkably well.
Clearly it also brings a contested airspace utility which the A-10 (and nearly all other fast platforms) lack. We can all argue until we're blue in the face about the usefulness of stealth but it has a quality of its own, applicable to every mission it does.
In time the increasing weapon type clearances will add to the CAS load outs possible. I'd compare F-35 CAS capability more to F-16 and F-18 and not A-10. Primarily not designed for 'in your face' gunnery and no Ti bath tub etc.
