I don't see what's so hard. They do it with their Kobe's.
They have minimal branding, which is great for them. Create some new boxes and slash the prices some, since you aren't paying for the name or hype anymore. They did that with the 700's, besides the Waverunners.
If they sell, great, if they sit, it will be like their Stan's, Shell's and a lot of their inline stuff, but something is better than nothing.
Maybe they think waiting for an announcement will build up hype. IMO they should take them out of boutiques, and have them in regular Footlockers and Finishline's, so more average non-sneaker people can try them out for the first time. Maybe it will also draw people back to boost in the process.
