I imagine (but am just guessing) that we don't get Japanese art like these because of licensing fees. It might be more expensive to print these overseas that makes it cost prohibitive, or there isn't enough demand for them, or something.
Thanks, WPM! Finally a sensible answer to a much asked question!
Actually, free shipping coupons for the Japanese Pokémon Center would be cool rewards for winning Play! Pokémon events. It is sad that they aren’t more available, but when people complain without full awareness of the facts (which I will admit I myself am not immune to), the lack of awareness of the cause leads people to expend energy on complaining about the effect.
As for the Pokémon Center equipment we ALREADY have, I have to admit that the art style is a bit plain, but for the most part it rarely uses stock Sugimori Art.
And in the end, it is probably better that all this gear isn’t available in the west. The artwork is so outstanding that I have no doubt that some collectors would bleed their wallets dry trying to collect them all, so this way people have to pick and choose, which, although the cost-per-unit is higher, makes for significantly healthier bank accounts.
