Lumia 940 should be like Samsung's Note Mini edition.
I think this is how we gonna work :-
all phone allowed to use stylus (from 540 to 1540), doesn't care about spec, all Microsoft need to do is to add stylus definition on the touchscreen.
And stylus has...
- Selfie pen - instant selfie pen, same as surface pen with modify of side button
- top one for instant selfie capture. Hold for open camera app and automatic switch to FFC, when app is open, it will capture image, used for people who want has no one to help when capturing best selfie image on the table.
- bottom one for instant rear camera picture. same as top one, open app, automatic witch to rear, when app is open it will capture image, used for people who want to capture a family/friends photo during party/meeting etc.
- Working pen - Same as surface pen, no modify
- Shortcut pen - Same as Samsung's note pen, hold on screen will open shortcuts
- Modifiable pen - Same as surface pen, with extra 2 buttons, modifiable through Microsoft Stylus Hub for Windows Phone, able to modify what will system do when pressed button
plus all Lumia phone...

for Lumia 1040, use dual CPU because of 8K recording, Snapdragon 805 used for normal usage, Snapdragon 800 for image processing when recording
*if camera is more than 30MP, it will use dual CPU like 1040
