the only answer is Nintendo. Their home console/handheld are weak. They could only to aim current Sony devices and they will get the higher jump

Nintendo easily (both handheld and console). However as far as home consoles goes I'd still say that the next Nintendo console would be the "weakest" but not by much

Nintendo did have one console called N64 that had more power than Ps and Xb in the 90s but I do agree ever since they have lagged. They are already developing a new console that will be similar to Xb1 and Ps4. I do think they will lose supporters if they bring a new console out so soon. They do have a chance of reviving them with only the right move and that should be next gen and match specs or better.

PS1 launched almost two years before N64 and so did PS2 against GC/Xbox.

Among competitors, only the OG Xbox was really "substantially" more powerful than PS consoles.  I doubt GC was more than 30% more powerful than PS2.

OP:   Probably the Next Xbox. MS will try to avoid the mistakes of 2013.

Ouya 2.0 by far, no question

XD It's funny cause it comes from a sad story :(

Too hard to say, but I'm guessing MS learned a fairly bitter lesson this gen and will make sure the next XBox if they make one is hardware parity or better than the PS5.

Wow, opinions are more split than I thought. I imagined most votes would go for the 3DS successor, because of the lack of power of the 3DS.

Like others I voted Ms because I think because of this gen they'll react for their next console.

If Nintendo doesn't try and compete next gen then my hope for them is lost. So I hope Nintendo's next home console.
