I cannot give an answer to the question...I am not on the marketing or sales side of the company. Since we are now under new management things might be different for this upcoming release. (And, yes, Vegas Pro 23 is coming.) Offers, pricing, release date...all these things might be altered a bit this year.
I am hoping we will be able to soon announce some of the exciting things coming with VP23. The team has worked very hard to make some vast improvements over the last year.
Vegas has offered a 2-for-1 upgrade a number of times in the past, but not always. When available, it's usually in August but disappears the moment the new version is released. So if you want it and see it, grab it quick before you miss out.
