I think it unlikely.... I would bet we'll never see one.
OLED is achieving good yields at smaller glass sizes. Unfortunately, B&O has departed the smaller screen market at the current time only offering 32" and above. B&O would do a beautiful kitchen/bedroom OLED set that would sell extremely well with a 21-24" display size if they set their minds to it.
In the larger sizes, the advancement of standard LED displays is seeing it beat OLED out of the market IMOP. The broader industry and demand for display glass is demanding tighter pixel density which is being faster achieved on the standard display technology. Added to this, picture quality is being advanced more through higher performance picture/sound engines.
If I were buying a new TV now with a 1-2 year view, get the best 2D TV you can buy at this moment.
Its funny, but seeing the new Nintendo 3DS, makes me very confident that in 5-6 years time, we will transition to new 3D sets that don't require glasses. The current crop are great prototypes that demonstrate the potential, but the requirement for glasses ultimately make them 'test beds.'
I'm also sure that TV sets will double in resolution in that time down to the fact pixel density will be possible in these glass sizes and the display engines will be capable of processing and upscaling that level of data. Look out for 3840x2048 resolution displays. Added to that we will all hopefully have 50-100MB to our houses that will enable us to receive the quality of programming at this level.
Thats my crystal balls 2 cents.
