From looking around it looks like they are going to have 10 back grounds for us to pick from when creating a custom character. In D&D 5e when creating a custom character the backgrounds affects the number of languages you know, skills, background feature, and starting equipment.

If everyone speaks Common and there are not going to be any background features then where does that leave custom character backgrounds?

Watching the videos of the live events where they gave viewers the options to choose the outcome of an encounter its seems in almost every case viewers didn’t pick/do what was wanted or expected. Once they starting getting the data from EA and seeing what people want and where people are spending their time I have a feeling we are going to see a lot changes.
