I doubt Goblins will be added as a playable race and I actually hope not. At least they should be added after the likes of Aasimar (to counter-balance Tieflings) and Genasi.

"Racialized accents" would be good...bring on the drunken Scottish dwarves, please! Moar immerschion!

Difficulty setting should in my opinion be one of the biggest priorities now. There's a small minority of vocal people who take strong issue with almost any sort of RNG and advocate for homebrew, while there is a large minority of vocal people who take strong issue with excessive deviations of D&D RAW. Difficulty settings could satisfy both camps and provide more accurate feedback for the rest of EA.
