1) One unit that can handle both AT&T and Verizon SIM cards for 4G use.
All for that
2) Front facing dual stereo speakers.
Speaker grills on the front? I'm going to say NO.
I'm OK with the current speaker size and location; it is very useful. Stereo would be nice, but you'll need 3 speakers to be able to accomplish stereo on any orientation (portrait and landscape); otherwise not every user would benefit from it.
For all other needs I use either a Bluetooth Stereo headphone, AirPlay to Sound System, Portable Bluetooth Stereo Speakers, AirPlay to my Mac running AirServer with Bosé Stereo Speakers.
3) 128 Gigs of on board storage.
Eh... For me unnecessary but hey, I'll buy it.
The more, the merrier.
4) Anti-glare matte screen.
Bumps down the clarity of the screen. Maybe give us a choice between Gloss or Matt.
No glossy display could mean your fingers will not slide nicely on it. Flat may look and feel odd.
5) 8 MP back facing camera with 1080p and an LED flash ( or two ).
Eh... If I need to take a proper photograph or video, I'll stick with my DSLR.
6) Micro SD card ( or regular size SD card ) for extra storage.
NOT GOING TO HAPPEN
Without the ability to freely write to it, this addition would be mostly useless. A change in iOS would make this possible now with the Camera Kit.
7) Two headphone jacks.
NOT GOING TO HAPPEN
Make it happen now with a $5.00 1/8" stereo Y-adapter
😀
The truth is that I never use regular headphones with my iPad. It's too restrictive. Instead, I use Bluetooth Stereo headphones. I wonder If you could connect two.
Of course, none of the above applies when you want to listen with your GF cheek to cheek. the closer and shorter the headphone wire, the better!
😀
To me, the most important new feature would be for both the chassis and glass to be: unbreakable and unscratchable.
One feature no one has asked in a very long time is an ethernet port; true, it's no longer necessary. It can easily be accomplished with an AirPort Express in bridge mode. Heheh!
IR Port to be able to use it as a universal remoter without the need to buy additional parts.
And make the headphone jack both analog and digital like the MacBook Pro has. That would be a great feature too.

Whatever the gizmo is that allows for precise stylus writing/drawing
Make it a fine point stylus, not that thick as a sausage styli we have to use now.
