Yeah now that we've had confirmation on the classes and customisation, the possibility of other movie (and/or comic, figure etc.) skins being included either as unlockables or as future DLC is the question I'd most like to know the answer to.
Hopefully since we know we'll be getting Jungle Hunter that might open the door for other skins to be included, since if they were to sell DLC those would surely be the most popular/best-selling.
I'm a bit surprised to hear such unambiguous language regarding the '87 skin not being sold later. Like RidgeTop said, usually pre-order stuff is sold later but they just can't say it, or else potentially risk those precious pre-orders. We usually get ambiguous terms like "so, right now we're just focusing on this as pre-order content" rather than ever actually say "no, we'll never be selling this later." This was a bit more blunt, but I guess there's technically still some wiggle room there. Maybe in the days since they came up with a plan to sell it post-launch, so it's still technically and chronologically accurate (the best kind of accurate)!
But yeah either way I'll be pre-ordering, so no real worries there. I'm just waiting for any UK retailers to actually put listings up for a physical version. I'm beginning to think this could end up being a digital-only release over here.
