I see prog alive and well, just in a different more modern form.

Plenty of great math rock bands and progressive metalcore bands about. That's what really does it for me.

It all comes under a blanket progressive term for me but I realise they obviously don't sound much like Tool, Opeth & Dream Theater, which is I suspect what OP is getting at here. I'm sure there are plenty of bands like that knocking around though paying homage to them under the radar. I just wouldn't know about them as it's not really my cup of tea.
