Yes

306.4. (http://imtgapp.com/forum/index.php?action=imtg;area=rule;number=306.4.): If a player controls two or more planeswalkers that share a planeswalker type, that player chooses one of them, and the rest are put into their owners' graveyards. This is called the "planeswalker uniqueness rule." See rule 704.

Pretty much as Nymuera already said: yes

Thanks guys.
