I'd like shadow priest renamed neuromancer because of all the mind-based tricks they use. Shadow priest is also too close to warlock and maybe demon hunter.
many of you are thinking a little too forward about the names, generally i believe the names will only go to the specs which essentially have little room for creativity, a prime example of this would be a frost death knight, how do they build upon this without stepping on the toes of a frost mage? especially when the frost deathknight will likely become a more spectral/soul based and thus opening up a whole bunch of paths for new abilities.
paladins will not need any changes for example as their specs make full sense and warriors will likely change prot into gladiator.
You are probably right, but it's fun to speculate :P
