Expect Naughty Dog to Fix & Add Things
Naughty Dog's Uncharted 4 beta will evolve over time. So the beta that you see tomorrow won't be the same as the beta that ends later on this month.
The company hasn't said what it will be adding exactly though we expect the company to address some of the more glaring bugs and perhaps add some new items to use in the game. Betas typically feature several hot fixes.
Naughty Dog has said that this will be larger than an average beta so we're expecting it to be larger than your typical beta.
