I think the DPI is much higher on the 3DS than it was originally on the Wii (assuming you are playing on a 30 inch + television.) 

And for everyone saying it's being released 3 years after the original, it's much closer to 4 years, especially in the west. The 3DS was released early 2011 and Nintendo stated that the new 3DS won't be coming west "before 2015".

It actually sounds as if the games will be playable on the old 3DS, they just won't look as good.

It's nothing like the Xbox? It's a good move to refresh the 3DS somewhat to expand it's lifespan.

"The remake is something they’ve previously wanted to do for the Nintendo 3DS, but were not able to due to its lack of CPU power, but now that it’s getting a boost with the newer version, it has been made possible."

Where did Nintendo say that? All I read in the thread's OP is that they are able to port the game to the "New 3DS" with "improved graphics and controls" because of the extra CPU power, which means (in terms of a business) fewer costs, and therefore it is reasonable to port it to the "New 3DS." The question isn't whether or not the original 3DS can run the game at playable levels (it can), the question is how much would it have costed them to port the game to run at playable levels on an equivalent system (in terms of raw power) with a different architecture (the code was developed with the Wii hardware in mind.) It might've been too much in their eyes, and that is why they needed the extra cpu cycles, just so they could make a cheaper port. However, I think this vastly reduces their consumer-base for the game ( and others.) Xenoblade has a lot of potential in terms of sales, but Nintendo keeps giving it the shaft, first by limiting supply in NA and EU for the Wii game, and now by putting it solely on a console SKU most people don't want to upgrade to, but many people who haven't (and have) would love to play the game. The game should've just been bundled with Xenoblade X or rereleased on the Wii U for $40. It would've made more sense profit-wise, so the only thing this tells me is that this (and other games) are meant for people to buy the new SKU, which is just a blatant and annoying abuse of Nintendo's brand image in my opinion. 

Yes in a nutshell. But since its Nintendo ppl wil sugarcoat it, its like the Amiibo thing, where that a Sony or Ms initiative ppl would go nuts saying they were trying to explore consumers giving in game benefits to whoever buy Amiibos, but since its nintendo its a great move somehow.

Yeah because Amiibos don't give you ingame advantages, while Skylanders does. Its just a cosmetical thing and to save your save games and stuff.

jimquistion or what ever his name is will rip nintendo apart surely lol.

Well, that sucks, but it will probably only be ports of old games that can't run on the 3DS.
The internal SPD/EAD don't seem to develop new 3DS games anymore.
