Unfortunately, "all but promised" seems a bit optimistic.

The relevant bit starts at 14:30. What he said at about 16:00 was, "I would love to release something like this ... for the 25th anniversary." And it seemed pretty clear from the context that by "release" he meant "announce that we've decided to produce and sell", and maybe even have a prototype.

I hope I'm being pessimistic. I used Thinkpads at work for somewhere between 15 and 20 years, and I hate the removal of 3 mouse buttons and other keyboard changes in the more recent models.
