Ime, this whole thing is driven by the ability score system's cut-offs at 15+2 and 16+3. I've had plenty of players tell me that 15 isn't good enough for main stat.
The debate now is nothing compared to 2013 when 5E was hashing out how to do race ASI's and ability scores. It was a huge playtest then, much much larger than present; current WotC leadership has way less cred than Mearl's team then. Anyway, they tried linking ASI's to class, removing them altogether, heck even removing ability score modifiers entirely. After all permutations, we ended up with 2014 system - which was most acceptable then, and kicked various cans down the road.
Now WotC thinks market has changed and they can implement changes some of them always wanted to do. Personally, I don't think they're being anywhere as exhaustive or inclusive (ironically) as 2013. I am getting a strong 2007 vibe when WotC tested mainly in-house and pushed 4E. To total disaster.
I was sure D&D movie would be a hit, watched it twice, but the fans just didn't go. This OneD&D is no sure thing either. My group has no interest in buying it. My friends say the races all sound the same. Divorcing ASI's from race may still not be a good idea.
