I'm not so much worried as confused... but that's pretty much the norm with me. The one person here that got it ordered it... so I'm still thinking it's the retailor end.
Yeah, I can imagine how frustrating it must be to have to wait for people who order from the publisher. I don't really know what to advise there. As I said, I'm just one of many paid artists, I'm not privy to how the company itself operates.
You might be better off ordering from a comic store or an online retailer - someone who gets their stock direct from the main distributor, Diamond. The Diamond orders are the ones that keep getting 'sold out' (as the site proudly claims).
All that means is that the initial print run has been fully pre-ordered by retailers like comic stores.
If you have a tab at a favourite comic store, putting in a specific order for the Muppet comics will mean they can get in their orders as soon as Previews shows them and you'll get the first printings rather than showing up at your comic shop and just hoping they have them.
Mind you, that's just IF the comics get released as scheduled. My point was that sometimes the release dates get shuffled around for various behind-the-scenes reasons which are not the fault of the distributor OR any comic store.
If a certain title gets pushed back, don't worry, it WILL come out, all it will cost any fan is just a little more waiting time.
Again, I can imagine how it's frustrating, but they WILL come.
