I just waitlisted this and this being waitlisted might be the best thing to happen for me (in terms of collecting).
I have War Machine MK2 and I like it okay, but when I got it, it was the only option. I only want one War Machine but I prefer a bulkier version. So when the Mk1 and 3 were announced I went back and forth for a long time trying to figure out if I wanted to go through the hassle of reselling the MK2 while also not being able to decide which bulkier version I wanted. When the Mk1 got waitlisted it helped me rule that one out. The arms look skinny and looked like it might be way taller than the IM MKVI, possibly taking away from how good they would look together. So that just left IM Mk3 on the table if I decided to upgrade at all. The MK1 going on waitlist help me know I liked the Mk3 better.
Now, the question about if I want to spend $350 to upgrade when I have the Mk2 I still wasn't sure about, especially because I likely wasn't going to get all my money back for the Mk2. So the waitlist is the perfect solution for me as I can leave it somewhat up to chance. If it converts, I'll be happy with the upgrade and try to get what I can get for the Mk2. If it doesn't convert, I'll just decide I'll be content with the MK2 and celebrate that I saved $350 plus whatever I couldn't have gotten back for the MK2.
Despite not being as bulky, the Mk2 still is a beautiful figure. Sometimes when a better version of figure is available I can grow to dislike the version I have on my shelf. But I have never felt that way though about the MK2, which is why it took me so long to pull the trigger. So, now I leave it to the Hot Toys gods - may they shine favorable on me and do what is right.
