Can someone explain HDMI 2.0, and HDCP 2.2...

I am planning on purchasing a new UH 4K Tv shortly, and hope to optimize image quality and high bandwidth. I don't want an obsolete AV processor, or BD player. My current rig is all HDMI 1.4a compliant, with an Oppo 105d that up converts to 4K. The only processor I've seen that incorporates the new HDMI codecs is the top of line Integra 80.6.
I wrote to Oppo, and here is their response:

There is no need to support HDMI 2.0 or HDCP 2.2 since the player is an upscaling Blu-ray player. These technologies are only necessary when you want to use a native 4Kx2K player.

Can someone help me suggest timing/need to optimize my new processor purchase, from the current Marantz 7005 I now own, or whether it doesn't matter, and just be happy with HDMI 1.4a with up conversions and 4k pass thru. I am confused. I am hoping to stream native 4k content from Netflix, and Directv when available.
Thanks for your answers.
Maybe this article will help...
Thanks..just spent time at local HT store...the only pre/pro they sell that currently supports HDMI 2.0/HDCP 2.2 is the Integra 80.6. There are rumors that Directv will offer streaming 4k content, but will likely require a new set top box.
I think I'll wait until after this year's CES in January, and see what new models will be released, and if there are any discount prices on current version of 4k monitors. Seems like the new modded Oppo 105d I purchased won't be able to play new 4k BD discs...bummer...but if we have adequate streaming content, won't make a big difference. I'd like to pull trigger for upgrades for the holidays, but I think it makes sense to wait and let the dust and prices settle.
Given that Samsung has announced they are out of the plasma business, I'd be much more concerned about getting a plasma set rather than worrying about 4K support. If you already have a plasma, I'd consider waiting until OLED prices drop.
