Ok, I'll contribute.
Realistic Zelda's debut at E3 2004 was the Megaton.
Megaton refers to a megaton bomb. as in "Iwata Drop the Bomb"
After the Wii console was shown at E3 2005, rumors of a Megaton were around every corner, until the controller was revealed at TGS in Sept 2005.
Don't forget the "Reggieton"
