Hard to say if it's real or not, because this list is played pretty safe. It all seems very believable. Though aside from a horse no alternate mode of transportation? Something that can fly that may have been hinted at by Aonuma? Thats what I was waiting for, but then that will probably be the surprise gimick this time around.
EDIT
How do we keep getting bolded in aftermath that is Reggie?
Unlockable sword secrets? I'm calling it now, if this is the case Link will be able to use a sword whip like Ivy from Soul Calibur. Now that would be an awesome and a very differen't weapon than we ever had before.
Also I was thinking, maybe this leak isn't playing it too safe saying that the girl really isn't the master sword. She really really does look like it thats for sure, and Miyamoto did point out very clearly that Link isn't holding a sword, so maybe there is some truth to it.
