Maybe we should break it down into individual models...
1. One-time purchase:You get core SONAR + the default set of included add-ons. You don't get any additional updates. If you want to get the latest version with all fixes and new/updated add-ons, you need to make another one-time upgrade purchase.
2. Monthly/yearly subscription:You get core SONAR + the default set of included add-ons. As long as you maintain your subscription, you get the latest version with all fixes and new/updated add-ons as it becomes available.
3. Previous "loyal" SONAR users who opt for the lifetime deal: You get the latest version of SONAR + the default set of add-ons with all fixes and new/updated add-ons as it becomes available indefinitely. You don't need to pay anything again unless you want extra add-ons that are not part of default set of add-ons.
4. [Speculation] Free core SONAR with no extra add-ons:You get the latest version of SONAR with all fixes as it becomes available indefinitely. You can buy extra add-ons. If you buy the individual add-ons so that you have the same ones as the default set of included add-ons in SONAR Platinum, you will end up paying roughly the same as what you would for monthly/yearly subscription (or the one-time purchase, depending on whether the specific add-ons follow a one-time or subscription model).
5. New users and those who don't qualify for the lifetime deal:You can choose either option
1 or option
2, and maybe option
4 if it turns out to be true.
Now... I think people are concerned about option
3 because it implies CW will never make any money from them again. True, however that is a small % of the overall user base, and since the offer is a limited time only, eventually these "lifetime boomers" will go away and we will be back to everyone paying again. Plus it makes for an interesting experiment. And generates a huge amount of buzz and publicity.
Eventually most/all will probably end up with option
4, which allows people to try out SONAR for free, and then only buy the extra add-ons based on their finances and needs.
I don't think we need to worry too much. I'm more interested to know what happens on June 1.
