I think batteries, motors, and computer chips will remain a problem for Ford even for the Gen 1 product. Hopefully with their history and relationships they can make products appear, but it will still be restricting production.
IMO, the CT delay is due to 4680 production delays. Tesla simply can't meet the price/performance specs for the CT without 4680s. They could probably build a 2170 or 18650 version (sort of what Ford is doing w/ the Gen 1 F-150, using older tech with more modest range/specs but able to ship sooner) and then swap to 4680s when ready, but the price/range specs would not be what they promised during the reveal. I'm sure some people wouldn't care, as long as it's the realm of the F-150. But as
@texas_star_TM3 posted above, since they're selling all the Ys they can make, why force a model redesign if you don't have to?
