Nintendo finally announced the release dates today during its Nintendo Direct presentation for both the Wii U and 3DS versions of Super Smash Bros.
While no specific dates were mentioned as of yet, we at least now have time periods to look out for. Super Smash Bros. for the Nintendo 3DS is targeted for this summer, with the Wii U version arriving some time in Winter 2014. According to the Nintendo Direct, both versions of the game are still in active development, so there is just no specific date available at this time.
Nintendo did note that both games will be running the same character rosters and levels, so at least when the 3DS version arrives those of you waiting on the Wii U version will know what you’re waiting for.
