I am looking at BOUNTY HUNTER, JEDI, COMMANDO as possible professions. What's the latest word on weather these exist and what the better choices for the mentioned professions might be ?

All 3 are in, but no racial differences at all. Apparently a Bothan is just as tough as a wookiee- go figure. As for which 3, that depends on playstyle. if you're blind as a bat, might want to try commando witht he AOE weapons, accuracy is more of a plus and not a must ;)

the devs said some kind of 'Origins' would come with Ch7 to make the races different. Apparently  almost 4 months of time were not enough to get them done () so no racial advantages/differences...

"Race" is the wrong term, first off. (not that it really matters)

"Species" is a better term.  Well into Chapter 7, they do now have species-specific attributes.

I chose to be a Wookiee back before the first CU when species differences were in full effect.  Back then, you could even adjust certain stats based on your playing style.  I haven't bothered to check what the real differences are now.  I can't adjust the stats, and I'm not going to delete my toons and start over, so I don't care anyway.

Try creating a temporary human toon, look at stats, delete, and then create another temp toon of different species to see if the stats are different.  Delete again, rinse, repeat as necessary.

^^ They are wrong about there not being any difference in the species.  The stats of species vary.  There are just no species specials because the main station.com community cried because they all wanted the extra heal of the trandoshan, or to roar like a wookie with their bothan, so SoE said "cry more noobs you get nothing now" or something to that effect.

There are still some bonuses you can see in the modifiers list, but you won't see them at the creation screen.  Humans get a bonus to artisan experimentation, and another species I can't remember still hyperspace faster than others.
