Ps4 is selling better then Ps3 yes. But PS4+X1+WiiU sells worse then PS3+X360+Wii was selling. So total console market is shrinking.

Compared to 7th gen yes but you are saying it won't eevn sell as well as 5th gen consoles which looks unlikely. PlayStation Vue, Hololens and Project Morpheus might actually expand it even more.

My estimations for this gen are around 150 total maximum. (100 PS4+32X1+18WiiU). More realistical should be 130m. (80+30+20)
I'm amazed that people so sure that VR devices will expand the industry. Its expensive gadgets for geeks, technology fans which will be bigger flop then 3D TVs.

lets sing the doom song.

You're expectations are far from reality. Wii U will likely not sell 20 million, XB1 will sell way more than 30 million and PS4 will sell more than 100 million. Your estimations have no base and are way too random, far from what trends we have gotten so far this gen.

Not that much, actually. Overall console sales have been down every year since 2008 and this year will be no exception.

Only  PS4 and 3DS are selling fairly well, all the others are  in trouble. XboxOne is not selling as well and people expected and is ignored in Japan. Vita and WiiU are a complete disaster by now.

PS4 isn't just selling fairly well, but incredibly well for its price which hasn't been cut 2 years after launch. XB1 is doing better than 360 so its selling well. 3DS sold well before but Nintendo many so many revisions that its sales are rather unimpressive considering a the price of a 2DS and I think its drop-off in sales is because its hardware is weak and consumers are a lot more tech-savvy now than they were last-gen.

Vita and Wii U don't really need a mention.

Console gaming is stronger than ever. The games coming out are awesome, especially this year.

Dying Light, Evolve, The Order, Bloodborne, Witcher 3, BatmanAK, MGS5, Persona 5, StarFox Zero, Halo5, Xenoblade X, No Man's Sky, Battlefront, Until Dawn... and more.

Well, for WiiU+X1 is around 50 mln for me. It can be 20+30 if Nintendo will get some sales (which is unlikely, but who knows?). Or it can be 15+35 in other case. 
And if you sure that during 5 years of its lifespan PS4 will sell more than 100 millions - you're just fooling yourself. We can make a bet on it if you want. 

Why does it have to be 50 million? It looks like you just picked a sales number and decided that these two combined are only going to sell that much. That's random and inaccurate. They could sell 60 or 80 million units combined. I think XB1 would sell over 50 million units.

And how does my PS4 sales estimate considered fooling? It looks like PS4 will sell that much not in 5 years but lifetime.
