Upgrades to UHD Blu-Ray

OLED is the next technology for TV's, looks way better than UHD. Currently the 40" OLED are running around $3000.00 or more. This is why the 4k's are coming down so fast in price. Wait for 6 mons and see where the OLED TV's are then, in size and price. Oppo 105 already up samples all 1080P to 4K UHD. I doubt that Oppo would come out with another edition of the 105 they will probably come out with a much different model.

The few "new" things on the horizon are:
1. "Atmos" surround which brings new audio channels to the game. Specifically, you can hang speakers from your ceiling to enhance the sound field (a LOT of speakers from what I've read).

2. A new connection standard called "HD-BASE-T" that allows for much longer runs of HDMI cable (up to 350 feet give-or-take). You can keep you system in the basement and run HDMI to your TV in the living room, bedroom etc.
I think the current limit is about 30 feet.

3. New HDMI tech standards to allow native 4K (and 8K?) to feed your 4K TV.

Anything else?

Matt. I've got a very recent (1 yr) Panasonic 1080P plasma. I don't want to upgrade - just want the best feed for this, I think it's 52 inches. Very happy with blu-ray and hi-def from cable. Does up sampling from 1080p to the 4K mean anything for my rig?

4k is the HD TV where you have a LED TV with TONS of pixels packed in there. I think with your plasma TV it would make sense to have a Oppo 105 or something like that. Then all your blue rays would be upsampled to 4K! I think the Plasma would look stunning.
