Our friends in Japan have been enjoying Bandai's D-Arts Rockman X action figure for a little over a month now, but within one to three weeks time, we'll have him in our hands.
Within the next few weeks, North American retailers will begin to stock and ship out the localized D-Arts Mega Man X. This version touts English packaging (pictured) featuring Mega Man branding, and is said to be far more accessible to purchase than importing from Japan. What's more, Toy Arena and New Egg appear to already have the figure in-hand and ready to ship at a moments notice.
The usual stomping grounds for high-end Bandai products -- Big Bad Toystore and Entertainment Earth -- should be stocking X shortly. Of course, other stores intend to stock the figure soon, too. According to Bandai's Adam Newman, any comic/hobby/anime specialty retailers associated with Bluefin (Bandai's distributor in the US), online or not, plan on sell the figure in early June.
The English X will run around $39.99, but the price tag may vary a few dollars or so depending on the retailer. Just look around a bit and find a place that fits your budget; sounds like you'll have a lot of options.
