My thoughts.
1. Cakewalk is in financial trouble so they announce lifetime licenses to make fast bucks.
2. Gibson realises they wont make any future money since the majority of users is on lifetime license.
3. Slap together a new DAW using the core code of Sonar, make some visual changes, give it a new name and voila hey you can sell new licenses. Like heeey are you a previous user of Sonar. Then we got this FANTASTIC crossgrade upgrade you just cant miss!
4. The majority of the Sonar users get Studio One licenses instead.
5. New product dies.
No, I'm no genious and know nothing about anything so I'm of course totally wrong here but...
PS
I think we as consumers should be very suspicious of all companies who bombard us with offers. A lot of companies feel desperate. Just by the epic bombardment of offers I get from Izotope I really think that company is in financial trouble.
