Okay, you asked for it; language nerdism ahead:
What you're describing is "being screwed", which means being out of luck. (In this context, at least.

)
Getting screwed, OTOH, means getting actively cheated by someone. If Apple said: "Sorry, your code is used, go ahead and buy yourself a copy of ML at full price," *THAT* would be getting screwed by Apple. As it is, you may be screwed, because you have to wait, but you're not getting screwed, nobody had any intention to make you suffer.
If it makes you feel any better: I'm screwed, too, right now, as far as ML is concerned, because my iMac's video card decided to say bye-bye last night. Most likely, your system will be up and running with the new OS long before mine.
