In the interest of having a complete batmobile set, I almost ordered this, but I'm not a snyderverse fan, so I chose to hang onto my money. As everyone in this hobby knows, "hanging onto my money" basically equates to "I'll spend it on something else, that's just as frivolous, - and I will spend it, just not on this."
I know the first incarnation of the snyder batmobile appeared to be much more feature rich - you could upgrade the same vehicle to the justice league version with a fee for the interchangeable parts and have the capability of having either version to display without having to purchase two vehicles. That said, that was before WB licensing became necessary. Still, it was not a vehicle I was interested in, so I passed on it.
Fast forward to these two signature versions. When they were announced, I considered getting one, for two reasons that were not present with the first version offering: 1) The exclusivity of the limited edition and the signed plate, and; 2) Because some of the money was going to a very worthy charity, IMO. Never did I ever see anything announced about any updates, other than perhaps a metal axel or something like that for the steering mechanism, but nothing cosmetic or visually significant. I had always assumed that, aside from the exclusivity, really nothing had been changed from the first, unlicensed version. I could certainly be wrong on this, but again, that was my perception.
In any case, had I been a buyer, I would have probably dropped an email to understand what I could expect in detail. I've done this before on other vehicles, and I've always got a quick and complete response. IMO, if it feels like a cash grab, that's only because the time wasn't taken to confirm what was being purchased closer to delivery time when a refund could have been had, and now the purchaser isn't entirely satisfied. Even at that point before delivery, if I felt like that, particularly on a limited edition run, I would have still gone through with the purchase and sold it on ebay for a profit. Especially now with the holidays coming up and everyone out there looking for gifts.
As far as a "reissue" goes, I'm not exactly certain what that would entail. Both the BVS and JL versions are limited, numbered sets with the autographed plate, so I'm not sure how that could actually be "reissued". I certainly can't speak for Joost, but I have heard that because of licensing, Joost will not re-make the first version with the interchangeable parts. All that said, it's certainly his prerogative to open up sales again for either vehicle at some point in the future. Even so, if he wound up selling the BVS and JL batmobiles in the future, they would not be the snyderverse grails that these signature editions are.
