While it doesn't really matter to me, the OP is right. The end of the main story in 2.0 is just a cliff hanger into "season two".

Also, if you purchased 2.0 and continued to PAY for your subscription, after the release of 3.0, you really are not getting any new content without having HW installed. In other words, you paid for a game and a subscription to keep it fresh, and SE require that you purchase yet another game (3.0) in order to get the content you expect from the subscription you are paying for.
