Just to confirm - we are absolutely getting Gnomes, Ha'f-orcs, and Dragonborn. This is confirmed.
Just for my own interests (and without any offence or challenge intended), can you give me a source for that ?
Whether or not the source confirms these 3 races specifically (as opposed to a more general "all options from the PHB"), I don't fully remember where this may have been confirmed, whether it was a recent communication I missed, etc.
