First I just want to say that I think the new ISD expansion is a home run, grand slam, no doubt about it. The upgrades we've seen so far look great and the paint job is stellar! I think FFG will have no problem selling a ton of these units, probably even to some who don't even play Armada.
That said the recycle of the old model is worth pondering over. When I first saw the article and noticed the models were the same I quickly shrugged and moved on. It didn't matter all that much to me, probably still doesn't. But after some consideration, and seeing others touching on this topic in other threads as well, I think it's worth questioning "why did they reuse the original ISD expansion model?"
A number of reasons have been put forward. At the forefront of these is "the need to make money". But that argument rests on a false premise that only by recycling the model can they reap any profit. If that were true then virtually every new ship expansion they create, such as the brand new mc75 wouldn't make much money. So that can't be the case.
Perhaps it's that "they can't make AS MUCH money" producing a new model, but I have my doubts about that scenario as well... I'm not sure what the costs of producing a new model would be... I'll assume they are significant, but so much that recycling the old model is clearly the way to go? I have to imagine that producing a whole new model would have outweighed these additional costs by way of ultimately selling more units. The Chimera design is beautiful, but ultimately not something I care much about. The main selling point here it seems to me is the cards, and that will probably be enough to sell the majority on this expansion. But for those who are ok with their existing ISD expansion and cards, paint jobs probably won't be enough to sell them on this expansion.
There is still plenty of reason to buy the original expansion. It comes with some pretty good cards that get regular usage(avenger, boosted comms, Vader). There is also good reasons to buy the new expansion(Cymoon, Kuat, VADER). So keeping some ISD's at the warehouse and then either packaging them as the original expansion, or spraying on the Chimera pattern then packaging them as the new expansion depending on which expansion you need at the time makes sense from a supply chain point of view and thus an economic one as well.
But there are dangers in sacrificing aesthetic values for economic ones. Something I keep hearing both players and onlookers of the game remark upon is "how amazing the game looks on the table". With ships of various sizes and squadrons duking it out for victory amidst a backdrop of asteroids, debris, stations, and the blackness of space, one has to admit, the game looks truly spectacular. And so I can't help but feel that the recycling of the old model is somewhat of a missed opportunity in this regard, to add to that rich and vibrant tapestry. The irony btw of packaging Thrawn, one who deeply appreciates art and aesthetic values along with a recycled model merely painted overwith the Chimera pattern, is biting. The Chimera design is decent, but not much in the way of adding anything truly new and exciting to the battlefield. Most people could probably hire a third party to put the design on one of their existing ISD's for not too heavy a cost. But a brand new model fully painted is probably out of the reach of most players. At the same time, an ISD l such as that from rogue one, is something players have been clamoring over for some time now.
Anyways, I'd love to hear others thoughts on the matter, or from those who might be able to better shed some light on why it was done this way.
