Sony sells the PS4 at a small profit or one game scale. What is Nintendo's excuse now? Having a system on par with the PS4 would be a lot more profitable than putting out one of the worst selling consoles ever. Completely faulty logic that they cannot put out a strong system because it would put them out of business. Their price point strategy is killing them right now. Really, Nintendo would be dead if they hadn't lucked into the Wii being inexplicably popular due to a gimmick. That would have been three shit offerings in a row. How is that good business?
The PS4 didn't sell at a profit at launch - it may now with the cost of the hardware having gone down since it launched. It was definitely closer to profitability than the PS3 which some speculated cost them around $900 to make per console when it launched.
Oh and before you make the stupid excuse the wiiu wasn't selling because it doesn't have enough system sellers, the PS4 is breaking every console record with only one elite first party title.
Couple factors at work here:
1) Despite very few good titles on the PS4, they do have one in Destiny that people have been looking forward to that appeals to the biggest audience, the dudebros. I assume you are referencing Infamous Second Son, which really didn't sell that many copies in the grand scheme of things.
2) The illusion of scarcity - if people think something is hard to get, they will grab it the first chance they get (This worked on me, I knew I wanted a PS4 eventually for Destiny and JRPGs from the likes of Square and From Software - and I just happened to hit Amazon at the right time a couple days before Xmas and was able to snag one when they were in stock for about an hour).
3) Microsoft shot itself in the foot before either console released and Sony capitalized with clever PR and Marketing - thus converting a large chunk of Xbros over to the Playstation side.
Neither console is worth owning at this moment but Destiny is very promising. I really just use the PS4 as my Crunchyroll machine at the moment.
As for the Wii U, I'd wait until this months NPD numbers - I think it will have sold a surprising number of consoles. Between Nintendo proving it wasn't dropping support by announcing tons of upcoming games into 2015 at E3, Mario Kart 8, the $200 refurb deal on Nintendo's website, and just a general breaking point of good games now available (seriously it has like 5 games with an 85+ metacritic score). The MK8 Bundles flew off the shelves and just casual checking at Gamestop, Bestbuy, Walmart, etc and anecdotal evidence on forums like Neogaf - it seems to be sold out in a lot of places.
The new Xbox One SKU without Kinect will move a lot of units this past month also
Also, that 60 fps 1080p line is pure bullshit and you know it. Any AAA cross platform title would bring the system to is knees. Nintendo doesn't have to worry about that though since they were smart enough to piss off every publisher.
It's plays their first and second party games at 60fps, and that's really all Nintendo planned for it to do. They build their hardware for the games they want to make, not the other way around. But's its always been that way (example, the only reason Sony made the original PS is because Nintendo rejected their new CD format) and is the major reason 3rd parties don't develop for them any longer. The other reason (at least for EA) is they refuse to build in systems like Origin into their Operating System and now EA is blackballing them on all titles, not just AAA cross platforms.
