I really don't think there is any chance that they will make different classes for Fighter, Warrior and Fighting-man

It's clear that these are just name variations of the same class.
I also really doubt that Priest, Mage and Thief will be separate classes.
Racial classes might be in just as they might be out. It will be a political decision... but may also depend on how solid will be the multiclassing rules and how many options will the corebooks provide for class customization, because there may be little reason for an Elf class if you can make a well-working archer/wizard with some "elvish" extra add-on for example.
My take:
*tentative because I have no idea of what it was
