Whenever it is, I'm sure it will come before the 28th, investors love to see the reaction of the fans (as long as it can be translated into money XD).

PS3 had only life cycle of appox 6 years only which was launched at 2006-07 to 2013 (PS4 launched). This generation going to be even shorter so PS5 will launch in 2018 Holidays with full PS4 compatiblity to catch up with their PS VR games and PS4 will still receive support for 2 more years like PS3 did, so ultimately PS4 going to get support around 6-7 years before Sony pulls the plug.

We can say same thing for Wii U also which had poor launch library even though it had more time for first party to get ready. These days AAA games need around 2-3 years so its not easy for nintendo to get ready for next year in 2 years even if they started development in 2014. So even if NX home console launched in 2016 then it will have same fate of poor launch library which is why im thinkg that NX home console will come in 2017.

I agree that NX will b cheaper or same as PS4 but wont be powerful than PS4.

Well, the point of the power upgrade is not to become the go-to system to develop, it's to be able to play multiplats without important downgrades. When the PS5 and the XBox Two come out, they'll be more powerful than the NX and become the standard, but by that time, Nintendo may have repaired their third party situation and gotten enough support to sell a decent amount of hardware.

PS3 was launch in November 2006 in US and Japan and in March in EU, PS4 was launch in November 2013. in US and EU and in February in Japan, thats 7 whole years, not 6. I cant see PS4 last only 5 years or only 3 more years, I dont see PS5 before 2019.

No we can't say same thing about Wii U launch. Wii U is Nintendo first HD console and they had big problems with HD development that directly affected Wii U launch and first year lineup, with NX they will not have those problems because now they are very familiar with it. Another huge problem was that they needed to make different games for 3DS and Wii U in same time, especially because 3DS had very bad launch and Nintendo invest great effort in new games (they released Mario Kart 7, Zelda OOT 3D, Mario 3D Land, Star Fox 3D in same quarter in which they launched Wii U) in order to save 3DS, and they done that but that effect on Wii U. But again with NX they will not have that problem because they will make one game in same time for both consoles, not completely separate like this gen, that means much more games. Whole this Nintendo unified plans are to prevent software drought like before.

You wrote AAA games need 2-3 years to develop, so if Nintendo start working on some games in 2014, at end of 2016. those game will be exactly 2-3 years in development. Development of Mario 3D game takes 2-3 years maximum, Nintendo finisheld Mario 3D World in 2013. and shortly after that they confirmed they working on new 3D Mario game. Zelda U port on NX is also almost certain, Pikmin 4 is nearly finished, Retro is working one new game from 2013. at end of next year it will be around 3 full years in development, and those are only things that are generally known, for all other Nintendo teams we dont know how long they working and on whats games they are working. Even only with new 3D Mario game and Zelda U port NX will have much stronger launch lineup than Wii U had with "NSMB HD", Nintendo Land and ZombiU, but i dont think Nintendo will launch NX just with those 2 games.

Saying that, Nintendo will do what's necessary to not make same mistakes like they done with Wii U, in this case bad launch lineup, if they can't prepare enuf game for launch and first year, they will launch NX in 2017, but all indicates that they can prepare good launch for end of next year and that they will launch NX then.

I think NX home console will have power around XboxOne power and in that case probably will have cheaper price than PS4, but again Nintendo can easily make console with PS4 like power or even higher in 2016. and sell it at same price or cheaper than PS4.

Yes,... Nintendo won't repeat the same mistakes... like having poor third party support since N64 in all their consoles. Or lacking launch of 3DS that they said they learnt the lesson, but then repeated in WiiU... you are far too optimistic if you think everything will go well and it will sell a lot.

Well Nintendo will always have smaller third party support than MS and Sony because most of Nintendo buyers buy Nintendo consoles for Nintendo games in in comparison with MS/Sony which lots a people buy them for third party. Also, third party always had worst sales on Nintendo platforms. I dont think Nintendo will ever have third party support like MS/Soni but definitely can have much better support than this gen, maybe like they had on GameCube or better, and Nintendo is doing staffs in order to have better support, better communication and better devs kit, better and easy hardware for developing and porting, cross developing for more than one devices...

I already wrote why Wii U had bad launch and 1st year lineup (paragraph down), and with NX Nintendo will not have those problems. I dont think I am too optimistic, I think I am objective beacuse all this things I wrote are based on facts and Nintendo plans with NX. You have to realize that current generation will be Nintendo worst generation ever, and Nintendo is changing and they changing lotsa things in order to next generation be much successful than this one, so that means correction of mistakes that they made this gen.

Wii U is Nintendo first HD console and they had big problems with HD development that directly affected Wii U launch and first year lineup, with NX they will not have those problems because now they are very familiar with it. Another huge problem was that they needed to make different games for 3DS and Wii U in same time, especially because 3DS had very bad launch and Nintendo invest great effort in new games (they released Mario Kart 7, Zelda OOT 3D, Mario 3D Land, Star Fox 3D in same quarter in which they launched Wii U) in order to save 3DS, and they done that but that effect on Wii U.
