I have been a loyal ThinkPad clit user since the early 2000s and if they discontinue it entirely I will probably be more motivated to get a Framework for my next laptop.
As a product going after the MacBook Air, that's fair as long as the regular ThinkPads keep the trackpoint, even if it's a little vestigial. However I'd think of it as a regular Lenovo with ThinkPad specs. I just helped someone buy a 5 year old E15 that's got a bent corner and more than a few scratches in its black paint and I love how it looks and feels all the more for it! The screen could definitely be better, but as a beater word processor, it performs well and is satisfying to use. And that's the romance of a ThinkPad that they'd be foolish to let go of entirely.
I would consider myself somewhat of a power user but I still rarely use the Track point now that track pads have gotten much better. The Track point is nice to use when imaging one though since it works even when the ThinkPad doesn't have trackpad drivers
