I can't wait for E3!
From Nintendo
I know their canned their conference, which is fine, however I hope they have some good hands on demos for some awesome titles, like LttP2. I am also hoping an announcement of Bravely Default releasing this year! Doubtful, but would be epic!
Also, hoping they show off some Pokémon X/Y media. Maybe announce yet another special edition 3DS? We all saw the Pikachu one, and the Charizard one is coming, but maybe a cool bundle? A purple Mewtwo 3DS! Yeah right D: But, something else to provide more options and maybe a bundle would be cool.
From Sony
The PS4 being ~$400 o.o
Final Fantasy Versus XIII!!!!!!!!!!!!!!x999
I want to see a boatload of JRPG's for the Vita being announced for localization. We don't have enough, and Sony just recently held a poll and found out a strong majority of their consumer base wants more RPG's. So, make it happen!
