Backwards compatibility wasn't really a thing until Sony made it a thing with the PS2. Otherwise when a system was done it was done. Nintendo was like that on consoles until the Wii in 2006. I would have little issue with them skipping BC for the next console, as long as they were willing to port some of these games onto their next eshop. This is assuming they still find a way to bring the gamepad along. If they don't then I have no issue if the Wii U is the last of its old setup.

But if they do this, then they really need to bring it with the games. No droughts and every developer they have needs to be working overtime. 3rd party publishers and developers won't have excuses if the system is strong enough so along with their stuff Nintendo should be ok. But Nintendo needs to function as if they will never have consistent 3rd party support again.

No 3ds Games will be played in 3D...

This is one of the reasons why I think the 3DS will be a highly collectable items in decades to come!

As soon as no back compatibility in 3D will be confirmed. i will buy a few 3DS consoles as an investment!

They shouldn't bother with BC from the PPC consoles if it'll just increase costs, just start a clean slate. If people want Wii U games, then they should buy a Wii U, and that'll be that. And X86 for a handheld is a no, they'll go ARM, probably for both handheld and console, hopefully from ARMv8-A with the console including more cores and higher clock rates.

I've said that for years but it never happens. They shoudl have kept Rare and stocked it up with new talent. The IPS RARE had would have had better treatment that Micrososft gave them.

So the next best thing they can do is try to provide something for 3rd parties that woudl be easy to port and looked on part as PS5/nextbox and would require only small sales to profit. I think you would also see those  Nintendo guys who buy multiple consoles for 3rd party games, not buy two consoles and sales would increase. This also assume that the Nintendo system gets a onpar version (or close to).

The biggest problem that Nintendo have with third parties has nothing to do with power unfortunately. It's quality. Third parties know that they can't compete with first and second party titles by Nintendo in terms of general gameplay and most importantly, polish. A part of the reason why people don't buy third party games on Nintendo consoles in droves is because people owning those consoles are used to high quality products...whereas people owning Sony and Microsoft consoles are used to the idea of having games broken out of the bloomin box lol.

Recently, what have they seen..? Destiny. Broken. The Master Chief Collection. Broken. Assassin's Creed Unity. Broken.

The Wii 3 could be the most powerful console out of the lot next generation, sell a shitload and be dirt cheap to port games to and from but I'm convinced that third parties STILL won't give the console a fair shake because they know that they can't compete with the quality and polish of first and second party titles from Nintendo

They should drop backwards compatibility on consoles (but not handhelds) because it will cost them time and money that could be better spent elsewhere.

IBM recently sold their chip manufacturing facilities to GlobalFoundries and that includes the plant in East Fishkill, NY where the Wii U CPU is made.

Right now there is no interuption in production and contracts are there until the life of the Wii U, but if they wanted the Wii U CPU in the next console they would have to renegotiate with GloFo for the manufacturing and IBM for licensing the CPU tech.

Backwards Compatibility through Software emulation also wouldn't be perfect either, as seen with the X360.  MS had to make a emulation profile for each game and games weren't guaranteed to run perfectly.  

In the end I think they should just sell remasters or port the games to eShop for their next console.  But I do think the Wii U gamepad should be compatible with the next Nintendo console. 

The 3DS SoC is currently manufactured at 45nm, going through a die shrink to 22nm could be beneficial and could perhaps lead to putting in the entire 3DS SoC on the handheld and allow 3DS BC directly.

I have to disagree with you greatly. All of Nintendo's hardware has decreased in price very nicely and the components are very cheap. The reason WiiU is more difficult has nothing to do with the console's hardware and everything to do with the gamepad. The WiiU is already a single chip, it would not be hard or costly to have that chip refined to be in the next console.

The CPU would have to be pretty powerful. I can see 3DS emulation due to its architecture, but I doubt anything massive like Wii U emulation without including the CPU and/or GPU of it.
