Sounds like you have everything down, but here's something to consider. I haunt the Mego boards as well. Last year they entered into an agreement with Topps to produce figures, mainly ones that weren't as popular as say Superman, Batman etc. ST:TMP Spock was one. They were putting two a week out for pre-order and almost immediately the community started say "Whoa, that's 40 bucks a week, 160 a month" and started wavering. Something to consider, especially considering the economy.A lot. More than anyone ever did in the 1/6 industry. Not when they just starting out, I mean as of today. The most assortments a 1/6 company can release within 2 years. I can never ever challenge any 1/6 company in volume but I have strong confidence that EXO-6 can make a record in assortments.
Personal desire. I like to leave markings on whatever things I do, especially when I am a new comer.
So, be ready for some strong tidal waves (assortment), and also be aware that most waves are tsunami level (attractiveness). These waves might create some serious damages (eBay pricing because it won't happen ever again).
