Wii U Zelda/Metroid
We would have killed for the criminally underused Shigeru Miyamoto (seriously, did he not have more to show than the admittedly great looking Pikmin 3) to leap up on to the stage at the final moments of their press briefing to demonstrate a Wii U Zelda, Metroid, or simply anything which shows that Nintendo are finally taking HD visuals by the scruff of the neck to produce a Nintendo first-party title with the graphical finery of a Mass Effect 3.
