I think "final micro expansion" means that after Diplo the next "micro" will just be included in the $30 full expansion, right?
I'm not even sure what you are asking. There are 2 micro expansions. They will come together as 1 retail box. If (when) there is another not-micro expansion, it will likely have its own box I'd imagine. I've heard there will be discounts available to people who already own the 1st 2 expansions, in that the full expansion might also include their features... but we can't talk about it as if its confirmed.
