There's a price to be paid if you buy early ie you may have to deal with early bugs until they get fixed but you have the use of the new features straight away..
If you leave it too late to buy then you may miss out. I've always been an upgrade early person because history has taught me that when Cakewalk or any vendor changes their methods, it's the people who were in early that get disadvantaged the least. Sorry you may miss out.
On the other hand theirs nothing stopping you from contacting sales and asking if you can still get an upgrade. There might be a slip up with the change to the store, sales models etc.
