A bit more detail for the folks interested (I know I am)
If these documents are true, it looks like some tasty upgrades.
I'll definitely be upgrading my current P2 with a few of these parts but not sure about removing the self-centered spring sticks.
Improved motors - more lift and durability
Improved props - better efficiency and manuverability
Upgraded ESCs - possibly able to hander more current
Improved Transmitter - Left dial gimbal wheel (ABOUT TIME), Trainer port (for PC flight simulations), built in battery and status indicator
Compass - Protective shell (white), anti-static
