New 80" + 2D/3D HD TV purchase... HELP! (1 Viewer)

Hi everyone!
I just finished a room addition on my existing house for a home theater room. The dimensions are 20' x 23' with ceiling height of 10'. Light entering the room is minimal. I selected a 7.1 system with the following equipment: (I have selected and purchased my equipment already)
Here is the short list:
No Preamps or additional amps
Receiver: Denon AVR-3313CI
SubW: JL Audio f112-GLOSS (12" / 1500W)
Front Surrounds: Klipsch KL-7800-THX (150W)
Center: Klipsch KL-6504-THX (150W)
Side Surounds: KS-7502-THX (60W)
Rears: KS-7502-THX (60W)
My question is: I am looking for an 80" to 90" LED or Plasma 2D/3D flat panel HD TV for this room, which uses Passive Glasses (I think I want passive so no batteries/no recharging).
I want the best picture for 2D and 3D Blu-ray and DIRECTV HD. I can position my seating anywhere as I have room to go forward or back as far as I need.
Thanks for any input!

As far as I know the largest flat screen is 80" diagonal(Sharp). Have you considered a front projector? With the right projector, you can easily go with a screen size of 110" diagonal or larger.

I think Sharp has a 90" now. LC-90LE745U
I currently have a Sharp Aquos 65" Special Ed. I like it but I don't think it has one of the "better" pictures I've seen on other TV's such as Sony or Samsung. Now the one I have is 5 years old, so there are probably improvements in new models that will make a new TV better than the one I currently have. I have been happy with my current Sharp TV overall, but the picture quality seems to be just under par a bit. One other thing I do not like about my current Sharp is the shuttering of the screen in action scenes. Also I am thinking maybe go a little smaller in screen size (Not smaller than 65") and go with or wait for OLED? I do like the Pioneer Elite LED's they blacks seem really great, but again you get to a max of 70" but I think I could be OK with that.

Again, have you considered a front projector? That's a large room. Even an 80" TV will be small.

No I did not consider it as it will not work in my room. I am using theater seating such as Media Home Theater seating (5 seats) is a curved configuration (Items # MELLOW3). This is about 16Ft wide, 4Ft deep. I am putting a poker table behind the theater seating. So I will have the seating about 9Ft to 11Ft the 80" for what I assume would be optimal viewing distance. I’m using all in wall speakers for the fronts and center, and ceiling speakers for the rears etc. So a screen really doesn't work for my use of the room.
