What are you talking about? Have you seen pc's over the last century? Games can be played on specs 20x apart, one might be on 720p the other in 4k and so many other settings. Just by swiping a litle slider. 

Games that nintendo has already achive compatability with handheald and console. First and mainly, super smash bros. wii u is more than 10x the 3ds. and they kepet everything the same execpt the resolution. xenoblade chronicles is close to an example, is wii to 3ds, but the wii is still much more powerfull than a 3ds. There are probably others that I dont know about but thouse 2 should be enough.

STreaming to smart tvs on chrocast like devices is tota trash and Ive tryed it. there insane lag not sutible for gaming and the upscalability also suffers. So no, it would be insane for them to make streaming the default conection to a tv. If there is a docking station the even less likely to be streaming, since your setting it next to your tv, might as well conect the hdmi to it. 

and its true about the handheld owners not getting the console, but it also works the other way around. there are many wii, wii u, gc owners who dont like playing on the go and forcing them to go mobile is also not wise.

You seeem to be under the delusion that only the eurogamer rumor can possible be true. You need to get off that cloud. specially since they have been proveen wrong before. as far s you know that source that spred things aroud was send by nintendo to send everyone off track the real nx and for people to ddisregard real leakers. All im saying is that there is a world of possiblitys and 2 seperate devices is one of the more possible ones.

Nope what the are two views on what NX is one is that it's a hybrid and the other is that it's a home console with a controller that's slightly more stand alone than the gamepad.

Handhelds can already connect to home consoles btw they've been able to do it since the GBA and GC, PSP and PS3 did it as did Vita and PS4 and even 3DS and Wii U have done it for Smash 4.

That's very insulting and rude to alot of people. 

Nintendo also said that the Nintendo DS wasn't replacing the Gameboy Advance.

So you're thinking this is an ultra powerful Wii U that takes cartridges and has removable sections from the new fancy tablet controller? Great. I hope you expect this thing to bomb like the Wii U did.

I really cannot wait for this thing to be announced so all of the people that think they know so much can realize how wrong they are.

All I have to say is that some people on this site have seen, used and know what the concept behind the NX, but their NDAs prevent them from talking about specifics. I'll just leave it at that. Anyone you're getting information from either doesn't have any personal experience (because they'd have to sign an NDA to get it), or they're getting it from a second party that may or may not have the information they claim to have.
