I doubt we'll get the setting-specific races, like Eberron warforged, or any of the planeshift races, but chances are good someone will mod them in eventually. I'm really just hoping for all the PHB races at this point, I would really like to be able to look at and give feedback about dragonborn. (although i think dragonborn will be a big point of discussion, with many differing opinions)
Also please give us more planetouched, the aasimar and genasi.
Dragonborn are tied to genasi, period. When Toril and Abeir merged they both came to faerun. So i don't know where there is reason for a discussion. Everyone has races that he or she dislikes. That's what choices are for. But i am looking forward to those discussions

Genasi has already always been in Faerun.
Nah,
I have been around a pretty long time and read almost all novels that are around. Genasi popped up some time. I can't even say when exactly. I think they were around before the spellplague hit (spellscars would be fun too) i give you that.
But the most recent would be the introduction of thymanther and akanut during the merging of abeir and toril. So i say if we get genasi, we get dragonborn too. But it's larians game so we will see. The more stuff we get , the harder balancing will be. More balancing = more work -> more time and money.
Thats why a lot of mmos get simpler and simpler
