Project Roadrunner: Not in any way related to Project Butter, this is supposed to decrease the Android OS's energy consumption to allow for lighter, thinner phones.
Quick Settings: Not much new here if you're running ANY ROM released in the past 6 months. Just gives you more quick toggles.
Increased Security: LOTS of security upgrades, SELinux, VPN Lockdown and SMS Conformation.
(Love this one!) Multiple User Accounts: You'll be able to log in and out of different user accounts on one device. Not sure how I, personally, would use this, but I'm sure many of you will probably benefit from this feature.
New GMAIL / Gallery / Google Play store: Standard upgrades.
Of course, the news team will be keeping a close on eye on the event next Monday and will keep the community posted on any breaking news!
