A comment for Paizo - the lower MSRP for each booster means my local FLGS is willing to stock these on speculation - and they're selling rapidly - where he can't stock the Pathfinder boosters because people in my area just won't buy a booster at that price point.
Interesting you should state the MSRP being the reason the FLGS will stock these and not pathfinder battles:
MSRP for these 15.99 per booster according to Set one solicitation by wizkids
MSRP for Pathfinder Battles 15.99 per booster according to Lost coast solicitation by wizkids
Paizo should examine this set and have some serious talks with WizKids about options for quality improvement. Both the separate-flying-bases, and the fewer paint steps (and resulting reduction in paint-step-related flaws).
Many collectors view less paint steps as a bad thing. For instance, I think the needleblight looks like it needs 2-3 more colors before it will look like wood, and the dragons look much too 'clean' - the ones I have seen in person have little to no shading. They look much to bright where there should be a wash or something to show off shadows, and very little highlighting was done. Things wizards has done well in the past like making horns on the blue dragon look like horns do on real animals by shading the bottom didn't happen. I do like the Red Dragon, but that's because it got the shading on the wings that the others didn't.
Separate flying bases... I could take them or leave them - when I have 500 of them in a box, I don't want to dig through that many almost identical bases to find the one that fits this figure correctly. I have had 2 PF battles minis break from when removing them, but nothing a little superglue couldn't fix in 30 seconds I think for the large flying skulpts in this set it made sense, but if they include it for mediums figures, the actual figures will get lost in collections.
