I need a history lesson....08 bumblebee?

I'm relatively new to transformer collecting (I've amassed over 50 MISB figures in 2 two weeks...yikes!) and I've noticed all the hype surrounding the deluxe version of the 08 bumblebee and how hard it has been to come by. I did manage to get one.
Can any of you veterans out there give me any past examples of transformers that have generated this much hype before they began to eventually hit enough stores? How long did it take for people to finally obtain them....or maybe they never hit enough stores to calm (forum) people down?
What are past examples of some highly anticipated transformers and what ended up being the outcome? I am looking for examples of ones that were actually out on shelves in sparatic amounts but no one could seem to find them. For example, was classic starscream from 2006 like this? Just a guess?
I keep reading comments like...wait two weeks and they will be on shelves everywhere...I'm curious if this has been the rule or the exception in the past?
