I don't know who on the Team picks case ratios or if it's collaborative, but I have to question their thought process on it. Just to use figures as an example, I really cannot fathom why a new wave doesn't have the first case packed with 2 of most of the new characters and then packed lighter on the revisions, if they do revisions. Not ever new character in a wave is going to be a hot seller, but even collectors can make a good guess on what's going to peg warm from each release, why can't Hasbro figure it out?
Same with vehicles. There's no reason not to have a case with 2x Snowspeeder and Cloud Car and then come back with a revision with one or the other plus repacks and a revision of the other new and then repacks. Yes, I understand that they cost out each case on its own, but if selling a full run of Snowspeeders, for example, at $24.99 each isn't enough to justify the cost of tooling it up then there may be bigger problems.
But if they have to include that many repacks, why not the Corporate Alliance Tank? That's never been easy to find. Neither were the Vulture Droid or V-19, at least not around here. So why not get them out again before going to the JSF well, especially since they're going to be re-painting and shipping the hell out of them later this year anyway?
