I remember the first couple days after announcing the SONAR, web site was showing that you could upgrade any sonar producer to platinum for $149. If I am wrong please some one correct me....
I do have the sonar x1 producer and sonar x3 studio, so when I want to upgrade to platinum, web site shows I have to pay $199 which I think it is calculating based on x3 studio.
Is there any link available to show all the prices individually based on the different products?
Thanks

The $149 is for upgrading from X3 Producer only - older versions of Producer upgrade for $199. Any version of Studio upgrades to Platinum for $299. So it looks like you're seeing the correct price...
