If anyone hasn't figured out that Sakurai LOVES playing these games with us, you all need to learn REAL fast. Until Sakurai reveals Ness' update or we all get Brawl and he isn't there, stop assuming things. You all read WAAAAAAAYY too much into his updates, just take them as they are, it's a moveset update. Nothing more nothing less...
BTW, here are the other languages translations of todays update:
[SPANISH]
Surely you agree Ness, a character that appeared in previous editions of Smash Bros.. Well, Lucas is very similar to it. In fact, come from the same family of users of ISPs.
However, his style of fighting is quite different, because they do not have the same moves.
[FRENCH]
You know Ness since its appearance in the series Smash Bros., you will soon adopt Lucas, very similar. They belong to the same family of characters PK.
They have not the same style of fighting physics. What I mean is that they do not use the same standard moves.
[ITALIAN]
Lucas is very similar to Ness, a character who has always seemed so far in the series of Smash Bros. .. Both use the Psico powers.
But their way of fighting is quite different. And I mean that they do not have the same standard moves.
