morrowind went on sale about 3 months, I think it was after release. the price didn't permanently drop until few months ago, but it did go on sale, so yes. summerset WILL go on sale eventualy. however - after june 12 - it will not include morrowind and it will STILL be $30 for the basic edition. so.... decide for yourself if you want to wait for it to go on sale, or get it now. morrowind is a promotion. its not free as in you have to buy summerset and you have to buy it before june 12 to get it, but it IS a no extra cost perk. for now. its mean for people who might be on the fence about buying summerset now rather then waiting, people who may still not have morrowind yet. its meant to encourage them to spend money now, rather then later.
I mean... its not like this is the first time. a lot of games, both single player and multiplayer offer perks on form of extra content with preorders. extra content that you will have to buy separately once preorders are done. I don't think Dragone Age 2 was the first one to do it, but its the one that comes to my mind as the early example (I'm talking about exiled prince), but its been happening with a LOT of games.
this is a VERY common promotion and NO one is getting ripped off by it.
that said... anniversary event is about to start! bring on the motifs and plummeting prices and that delicious delicious double xp
