Just remember guys. Don't panic!
The software will keep working in the state it's in. If in doubt, upgraders can use current projects in older versions of Sonar (it's backwards compatible), and we can all start demo-ing other DAWs in the meantime. I downloaded Reaper and Mixcraft this morning, and I'll be keeping an eye out for Black Friday deals.
Best case scenario - Gibson will see the error of their ways and keep Sonar alive.
Possibilty, someone like Microsoft might buy up Sonar (though that is often the kiss of death...remember Nokia).
Worst case, Cakewalk will cease to be, but the DAW will keep working.
Gibson HAVE TO respect the yearly subscription agreements (it's contractual) or face lawsuits, so there must be some plan put in place for current users. Sure my lifetime subscription doesn't mean **** now, but at least I got a good year of updates under my belt.
