In regards to "iS nInTeDo dOoMmed???" - Nintendo as a company is in a much better position than Sony. PS4 is SELLING well, but pretty much none of the other products are and they are in serious debt. The PS4 would probably have to do as well as the Wii to get Sony out of their jam. Not to mention they are completely giving up on the Vita, while Nintendo is at least improving the Wii U and as a result, improving it's sales.
And while Sony has some interesting games announced, most of their exclusives are either timed, indie, or coming in 2015. In reality, PS4 has A LOT less games right now than the Wii U does. I own both, so I should know. I've got hardly any PS4 games, but I have about 10 full price Wii U games since it launched, and have more I still want, not including the future releases. That's actually probably the highest rate of retail game purchases I've ever made for a system, actually!
And while Microsoft as a company is above Nintendo, Xbox One is doing terribly, and again, hardly has any games. Much like Sony, a lot of what they announced at E3 and Gamescom was a timed exclusive, an indie title, or coming in 2015.
And I don't want to be that guy, but a lot of the games Xbox and Playstation showed off at E3 were really hard to distinguish from each other, a lot of them looked like gritty shooters.
