Panasonic has 3 models of televisions larger than 65" which are available to anyone right now. All of which can support 3D, or have a version which can support 3D.
Their 85", 103", and 150" models.
But, the price jump to the 85" from the 65" is stupid.
(MSRP)
65" Panasonic: $4,299.95 (65VT30)
85" Panasonic: $30,000.00 (85PF12UK)
103" Panasonic: $49,995.00 (103PF12U)
152" Panasonic: $500,000.00 (TH152UX1)
Hopefully, the 85" model you linked to, which is a 'consumer' version of their 85" display, will be more realistically priced, but I would still expect it to be about $10,000 and would be extremely suprised to see it with an MSRP lower than that, no matter how awesome that would be.
Their 85" size is probably my favorite from them. Stupid big, but really, on a big wall, it fills it nicely without being as imposing as their 103 or 152 models. If money was no object, I would likely get that over the larger sizes they offer.
Of course, at $30K, money is definitely an object.
