Upcoming update for Windows Phone 8 Leaked

Reddit Regular I_SH*T_KARMA, who has been pretty reliable with Windows Phone leaks, have posted the supposed changelog of Windows Phone 8 GDR3, the next minor update to Windows phone.
He writes:
So here’s what’s coming in GDR3:
  • Orientation Lock
  • Driver Mode, will turn on automatically when you connect it via Bluetooth. Can reject phone calls / sms and send auto reply back
  • Ability to have 3 medium sized tiles in a row
  • 1080p / new SoCs, which we knew for quite some time now
Other features that are currently being tested and are likely to be pushed to GDR3:
80% chance
  • Ability to actually close the apps via multi tasking
60% chance
  • Silent NFC (meaning no more constant confirmations for pairing something)
Please don’t ask for source, there is none.
There is nothing too dramatic or revealing in the information, with much of the features what is needed to support the new hardware the current smartphone market demands. Joe Belfiore has said recently that much of their work is currently being targeted at expanded the new hardware Windows Phone supports to enable new sales, rather than creating features much in demand by current users.
At the same time though Microsoft has promised an enterprise feature pack early next year which will bring support for features like VPN and encrypted email, and of course Windows Phone Blue, the next major version of Windows Phone, is expected to be a much more significant update
