I'm dreading/anticipating all the future releases, and the wallet is most definitely emptying quickly now. I can only imagine in 2 years.
I'm just starting to get into the customs too, and they ain't cheap
But I will be first to say that I will put the BTTF line before anything else being released

. I'm just hoping there is a DX Marty, hopefully similar to the DX Luke, in the sense there are two full figures included. But with 1985 outfit and 2015 outfit as opposed to the clean and BD. And I feel every protagonist needs it's counterpart, So I would definitely be in for Biff. And we can't forget good ol' Doc too. I would even be inclined to pick-up a DX Doc c/w with a few outfits and an Einstein/Bed combo. Especially since Einstein was technically the first to travel through time.
The delorean for me is also an easy decision, I would definitely be hanging it from the ceiling
