This may just be my optimism getting the best of me, but I feel like this is a test to see if Marvel moves the needle in TDLR. OLC has been very reticent to add Marvel to the Resort and this could simply be a test so that they can survey guests and gain information from moved merch.
I'm really not all that worried at all about IASW permanently having this. I think the more likely thing is that this small thing could theoretically end up with a full scale Marvel ride or land being built if the response from guests is that they want more Marvel in the parks (and merch is up).
