Nagini vs. Fawkes?

On the page http://parentingteens.about.com/library/sp/harry/blharryrumor-6-index.htm I found a rumour  that Fawks may be Gryffindor-Animagus.
So perhaps the final battle between good and Evil will be played by Fawkes-Gryffindor and Nagini who is Slytherin-Animagus?
Perhaps there is an indication that Fawkes was reborn in July on Harry's year of birth? I have not found it - perhaps missed it?
