Well, it's more about the distributor, I think. Here in New York City, we've got some big box retailers, some large comic places like Midtown Comics and Forbidden Planet, and little comic shops. I mean, some larger comic shops will deal with Bluefin directly for Tamashii stuff, which I assume will include DX and HMR stuff, but most small places will deal with Diamond after Diamond sources it from Bluefin.
As for Target, yes. The larger stores will sometimes sell spidered (enclosed by loss prevention device) high ticket items upwards of $100-$200, although these days they are more often Hasbro US releases of Takara/Tomy Masterpiece Transformers than anything like Gundam stuff. The question there is whether they already deal with Bluefin, Diamond, etc. as the lower-ticket Gundam stuff they do carry might be via one of Bandai's other distribution channels.
For brick and mortar, the relevant question is whether Bluefin tried or is trying to solicit this new stuff to Target, Walmart, Best Buy, etc. I assume GameStop might be more of a lock as they carried Yamato releases years ago and Toynami stuff since, but their web-sales division has been actively undermining their own retail store division's acquisition of figures stock, and it's affected their Gundam, Transformers, etc. stock in a big way. Buying from them is more like going to BBTS or EE now.
Anyhow, if anyone sees more solid info on shops getting them and not just websites, I'd love to know. To me, that would be a true revival in the US. 🙂
