Indeed it is as Sonicstate said that no one is going to pay for bug fixes, and if the update is not free the userbase will likely be split as it was last time. Because users who initially paid don’t deserve to be deprived of bug fixes.
Indeed a lot of the features introduced in 6.5 such as plug-ins were simply hype and honestly I don’t use “DJ EQ” or what not but improvement in areas such as comping were certainly welcome. Hopefully Steinberg have been watching Pro Tools developments which cater more toward CPU management and truly enhanced workflow rather than gimmicky “features”.
