I just read this...and...........

Battlefield Studios just confirmed that servers spun up in its "Portal browser" can be made persistent. Theoretically, that means the Portal browser will behave like a classic FPS browser, allowing someone to host a "24/7 CAIRO ONLY" server that won't disappear after everybody goes to bed.

This is major news that I am extremely excited to learn about.  This alone will make me want to purchase the game!!!
