This is the third rumor now. And actually from nintendo them selfs. http://www.neogaf.com/forum/showthread.php?t=469930&page=40ު http://gonintendo.com/?mode=viewstory&id=175521 After analyzing everything what happened and also a picture from the neogaf linked ign rumor thread i came to a conclusion. The name changed 3 times before going to japanese "mario party 9" text. This all happend in 15-20 minutes. Someone was in a hurry back there. Also the the system indicator was different back then, it was the empty blue Wii[japantext] and people said that means WiiWare ... it probably was a wii ware game but the WES name ...but i don't know if linked to mario party 9, i didn't saw yet anyone saying what it linked to before it was changed - i came to this like 20 mins after this rumor happend. I think this mario party 9 thing and the filled blue wii label is a smoke screen from the typos - ninjas at work - but who knows. Generally people already started to like the name was WES abbreviation would be finally something new - but they pointed out for the mass makert it might be a confusing name - though if WES term snaps on with people it should be fine for the hardcore audience. Personally i also like the WES abbreviation - there was a rumor back then that nintendo wanted to do everything to include "wii" into the name whatever it may be.
