Honestly, while I love Tri-X, I've left off caring what Kodak does with black and white. I'm done with them in sheets once my current box is used up anyway, and while I like Tri-X a lot in rolls I can move to HP5 pretty happily. One reason I like Tri-X is that I like it a lot in Diafine at EI 1000 or so, better than Delta 3200 or pushed HP5+. But last time I tried it I got EI 800 out of HP5. That extra one third to two thirds stop isn't that important and I can always push with something else or move to D3200 which I stock and shoot a LOT of.
TMY-2 IS a great film, very possibly the finest overall black and white film ever made, but for my purposes (maybe not for everyone's) my results on HP5+ in sheet film sizes won't be noticeably different. TMY-2 has finer grain but this will matter not one bit at the sizes I can and do print. TMY-2 has better reciprocity failure characteristics but I very, very seldom need that or care. (And if I do, nothing beats Acros though it starts out two stops slower and is itself very expensive in sheets.) Think of all the great images made by people like Adams, Weston etc. in days when they could hardly dream of a film as good as HP5, for example. Heck, if Kodak keeps pricing themselves out we might persuade Ilford to make Delta 400 in sheets again! (Better yet XP-2 Super! That would be awesome!)
Kodak has priced themselves out of the black and white sheet film market for my purposes, and if roll film follows suit, well it'll be Ilford's gain. I already shoot FP4+ and Pan F+ as well as D3200.
