I constantly buy stuff which later goes on sale, even though I try to be smart and catch them... as they say, timing is everything... you should see my Cake purchases!  
 
I look at it this way... never before could any of us dreamed of the power any one of the X series brings to our finger tips... and my scraping up the next bucket of duckets helps pay for all the hard working brains creating these amazing tools we couldn't have imagined we'd have available to us.
 
We're all contributing to advancing things along... and the age old regret of not waiting... will never end so I just don't go there... I'm glad it's here... and were paying peanuts for priceless advances in tools.
 
And, you don't need to upgrade yet... although... it's pretty f!!kin' awesome!!!!!!

I saw on the CW site somewhere that if you bought X2 within the past 3 months or more abouts your upgrade  to X3 is included.

I raised a similar issue, I purchased X2 studio upgrade in August, although different from this thread in that I believe X2a should still be more stable than it currently is, in that further patches and fixes such as an x2b should be still considered. X2 should still be supported for at least 1 year after announcement of X3 RTM...
 
In any case I bit the bullet and upgraded again X2 to X3 studio version (mind you it has only been 2 months since I last upgraded :( ) , I could see some biatching features that X2 Studio doesn't have that X3 Studio does, such as ProChannel and the ARA thing... 
 
Just got to get my head into it now and lay some tracks...

Enjoy X2 for awhile. Get used to it. Then down the road upgrade to X3. That way you can at least feel like you got some use out of it. Besides, if you wait long enough X3 will come down in price near the release of X4.

FWIW, in my opinion, early adopters always get the best value ultimately. They get to use the product for the longest and get the best upgrade pricing and deals. Waiting for a special is ok but I wouldn't expect anything any time soon. We ran a special back in July when you purchased where you also got Z3TA+ 2 for free. So you didn't just pay $99 for the upgrade, you also get a free synth. We try to be as fair as possible. SONAR X2 still works and is supported so hopefully you get a lot of value out of that and if you decide to upgrade later, it will be when you are ready to do so. 
 
Thanks again for your purchase. Hope this explanation helps.
