Just Sunday, I reported that 5 million players had logged on to test the Battlefield Hardline Beta. That number has now been dwarfed, by an updated total.
Announced on the game's official Twitter, it turns out 7 million total players turned up to play the cops and robbers Battlefield across all platforms.

This is likely due to Visceral Games extending the beta by a day, meaning it ran from February 3rd-9th in total.
I was one of those players, but form what I've heard, a lot of people didn't stick around for more than a few matches. That is purely anecdotal though. It will be interesting to see how many of these beta players translate into hard sales. We will begin to find out when the game is released on March 20th.
