NeoGAF has posted what appears to be a leaked feature sheet for Battlefield Premium.
According to the sheet, Battlefield Premium will run you $50 in the US, and members will be given "queue priority" on game servers.
Players will be able to reset stats, and it will contain all Battlefield 3 expansions.
All other information previously leaked looks to be accurate as well.
Earlier today, the EU PS Blog accidentally posted a date and pricing for BF Premium with the PS Store update. The site has the service releasing on June 4 - the same day as EA's E3 2012 press conference - and priced at £39.99/€49.99/AU$79.95.
A shot of the sheet is posted below.
