Well it looks like one of the bigger 3DS surprises for E3 has been let out a bit early--Tecmo-Koei is apparently releasing a version of Hyrule Warriors for the portable. The trailer was accidentally leaked on their Youtube page and quickly removed, but not before it was mirrored several times.
The new game looks surprisingly close in graphical fidelity to the Wii U game and includes new characters, such as Wind Waker's Tetra and the King of Hyrule. I really enjoyed the Wii U game last year so I'll definitely be picking up the 3DS version. Leaking a trailer early might be a bit embarrassing for Nintendo but color me happy in any case.
