Is that necessary?

You must have been 'trained' very well if you still cant see the problem with your comment.

At this rate I doubt it but anything could happen.

Edit: My opinion is about home console, I believe they will still have relevancy in the handheld market.

It all depends on what form this fusion console concept comes in. If Nintendo are genuinely rolling their handheld and home console development into one then their output will be very significantly improved, that alone will diminish reliance on third parties (that ship has sailed and will not return). At the moment, they simply don't have enough internal output to support two systems. All Nintendo's games on a single console though, that's a completely different prospect.

On the hardware front, give up the idea of a needlessly small and efficient console too because that is simply adding cost and pandering to a market that doesn't even care about home consoles any more (My power bill does not care if my game system uses 30 watts or 300 watts) Give up on expensive peripherals and put that money towards developing a powerful, and easy-to-develop-for, yet affordable, console. At a minimum start paying a little more attention to the western markets and standard requirements for online infrastructure.

If they do these things and throw in a little Nintendo weirdness just for good measure, absolutely they can be relevant.

Being relevant in actual gaming.

Ah, so it's easy for Nintendo to be relevant in regards to something almost entirely subjective that apparently hasn't translated into a real-world home console market presence in the last few years. Yay..? ^^;

i can recall last gen on here Wii fans claiming ps3 will do a dreamcast, look how things have changed.

i predict nintendo to be irrelevent with a home console next gen, 

It may since anything can happen :/

Yes, they will be relevant if developed good games:
-Xenoblade is the best JRPG the last console gen
-Bayonetta is the best H&S Game now
-Mario is the best Plattaform Game ever
-Zelda is the best Adventure Game ever
-Mario kart is the best KART and party GAME

-Pokemon and S. Smash B. are very popular.
-Splatoon will be very funny.

Yet given all that, this gen is still going to end up looking like this

PS4: 100+ million sold

XBox One - 32-50 million sold

Wii U - 17-20 million sold

So what does that tell us?

In the home console and handheld market- they will be less relevant- however, they may be more relevant in the mobile market-
