According to NintendoEverything Masahiro Sakurai stated that the work for Mewtwo as a DLC fighter for "Super Smash Bros." for Wii U/3DS has been completed and that he will be released soon.
He didn't mention how soon that is, whether it could be in a matter of hours upon the statement or within a week. Stay tuned to when Nintendo/Sakurai officially announces when Mewtwo can be downloaded either by code given to those who registered both Wii U/3DS versions of "Super Smash Bros." on Club Nintendo or buying from the eShop.
