best case: they don't and give us the wardrobe upgrade like we see in alpha/beta.
worst case: they'll inforce the starter restriction to both ftp and btp where they'll lock out battlegrounds and areas like some of us got when the bug for the lvl restriction was briefly lifted.
I was told that F2P bracket would be back. Concerning the classes, a lot of changes. The pala heal will not be able to do damages and the rogue could recuperate his shadowstep; that are the two mains changes whose I remember.
