Industry standards do change, slowly, but they do change. The usual signs of death throws when a standard is changing are already written on the wall. Avid just hasn't realized it yet.

Pro Tools used to be the only game in town in several key areas, like music production tself. That is no longer the case (hasn't been for years).

People keep forgetting sleeper things like FL Studio which has (allegedly) sold more copies than pretty much ALL the other "major" platforms out there combined. Granted, this is only for music production itself but it's still worth noting.

Multi million dollar facilities like huge post production places (mainly cinema/TV/major streaming stuff) will of course change the slowest because it's such a huge PITA to do it.. it's similar to the situation when we went from analogue to digital. Those places (and radio/TV networks) were the slowest in adopting the technology but it did eventually change.

Steinberg is playing quite a smart game with Nuendo, at least that's how it looks like to me. They have the Yamaha money behind it so there isn't a lack of resources to pull from. They are clearly going for the slow take-over and may very well be the next standard for the big facilities.

Don't underestimate the power of change coming from the young generation either. When they have all the key positions in the industry, things change. It's us old(ish) guys who stubbornly refuse to go with anything new (which is usually wise! Don't fix what isn't broken). Even just a decade ago people were still saying Linux will never amount to anything because it's open source/free and could never work! You don't find many agreeing with that sentiment any more.

Heck, who knows.. maybe Reaper is the future of all things music/film/TV!
