Nintendo doesnt dictrate when a new gen starts though.

Its the 8th gen now, and nintendo launching a new console, thats in no way better hardware wise than the PS4, doesnt mean its a 9th gen console.

Avg consumers dont care about what gen a console is.

They look at the product, compair it to others on the market and pick whichever they think gives them the best bang-4-buck & has the best game line up.

I dont think nintendo NX launches at under 300$ (which ps4 will be at this year holidays), and its game line up at launch will have to be very strong to pull consumers away from just buying a PS4 instead.

The SNES and N64 had a good balance of both. It's with the Wii that they started catering more to a younger / family friendly audience. They can certainly do it again, but it's going to be harder to do now as back during the N64 days, the was no Xbox and Sony was just starting off. Now they will need to cater to a different audience and also convince them to pick their console over 2 very well established ones. 

Timing indicates when a new gen starts and because of that, whenever nintendo releases a wii u's successor, it will be a 9th gen system.

You thinking the impossible scenario of a wii u successor weaker or on par with ps4 hardware doesn't affect the actual specs of the console and that's still irrelevant to determine the generation.

A new machine always has the potential to get the consumer attention, regardless of what's currently on the market. $299 is a sweetspot and it seems you're making overestimations over consumer preference.

I'm guessing the tech behind making an X1 must be cheaper now. If they stick with ddr3 instead of gddr5, they will make some savings.

I don't think they will go with BR so that might save money and they will probably make savings on a smaller hdd.

With the WiiU I think the tablet controller was a big expense. I can see them launching a £200 Base model. 

Sony's going to win this generation running away, it would take a miracle to stop that.

Nintendo should aim to overtake Microsoft at no.2 in consoles if at all possible, but even that will likely be very difficult.

The best thing they could do is to bend the rules of the game and make NX a never-ending, upgrading platform. As such NX would belong to no specific "generation".  

Sure, I agree with you. But 50m should be doable, even if they mess some things up. I mean, even the 3DS was able to pull 60m+ despite being overpriced/outdated/badly designed.

NX has no chance to beat PS4.
PS4 is the king of this generation!!!

Whatever NX is, it doesn't belong to the same generation as the ps4 and (like any console) stands a chance to beat ps4.

Nope, I am sorry. NX will be a 8th generation console as PS4 and Xbox One.

The NX imo will be a cheap handheld with a plug in TV what not. No 3rd party support because you won't be able to get 1080p res. Streaming from the HH won't do it.
