I see a lot posters here, and especially on N4G trying to draw parallels between the Wii U and the Switch. Both are significantly less powerful than their "competitors," and both are lacking in major AAA third party support largely due to those specs. They're also looking similar due to the limited first and third party support in the early months. The fact remains, however, that the Switch is not a Wii U. Actually, it isn't even a console, really. It's a hybrid, which is its greatest strength over the Wii U in terms of software support, sales potential, and dedication from Nintendo themselves.
Firstly, we need to look at the Wii U and 3DS. They both struggled early on, but the way Nintendo handled their failures was dramatically different. The 3DS launched with a boring, expensive gimmick that failed to excite consumers, a poor game lineup, and a confusing name to boot! When the 3DS failed to set the world on fire, Nintendo didn't even wait 6 months before cutting a whopping $80 off the price. This unprecedented price cut was followed up by a strong devotion of development and marketing resources to righting the sinking ship. Fast-forward nearly 6 years and, while clearly down from the DS, I think that most of us can agree that the 3DS has been a success.
The Wii U ended up in a similar situation. It also launched with an expensive gimmick, disappointing software support, and a confusing name! When disaster came knocking, Nintendo put out a Direct in February 2014 where they announced a great deal of upcoming titles, but it failed to have any meaningful effect on sales. In the months and years following, they pretty much just coasted by on the games that they had announced at that February Direct, with a few more small titles and HD ports to tide things over. The Wii U never saw a true price cut, nor did it see a significant software push from Nintendo. In fact, they took no significant action to jumpstart Wii U sales at all! Why? Because consoles are not a vitally necessary part of Nintendo's business.
Nintendo handhelds sell better than their consoles. This has been a constant dating all the way back to the GB/C, but is even more true today. Even during Nintendo's most successful console era, the Wii still failed to even come close to the LT sales of the DS. The Wii could have sold no units, and Nintendo would still have been in a good place. They are like the inverse of Sony. When the PS3 was in trouble, Sony threw astonishing amounts of money at the platform to ensure its success -- a move that they did not repeat with the Vita. SIE is perfectly alright without success in the handheld market. Nintendo, on the other hand, can handle a console bomb, but a failed handheld would ruin them.
And that is what brings us to the Nintendo Switch. The combination of all that is Nintendo. The immediate successor to the Wii U, and the eventual replacement of the 3DS as well. Soon the be the sole piece of dedicated gaming hardware that they have to offer. Given Nintendo's history, I can not imagine that they would treat this system anything like how they handled the Wii U. If they were willing to go as far as they did to save the 3DS, you can guarantee yourself that they'll go even further to protect the Switch. Should sales begin to falter, expect price cuts, expect new bundles, expect potentially dramatic changes to their business practices, because they have nothing else besides. They've gone all in, and must commit themselves to making the Switch a success.
This is why I feel confident enough in the Switch that I plan to buy one before the end of the year. It seems so many have been disappointed by the initial unveiling that they've forgotten what made the idea of the Switch so exciting back when we first started to hear about it. Regardless of what the launch lineup looks like, this system is guaranteed better first, second, and even third party support than the Wii U, and a laser focus from Nintendo as a whole should result in much stronger sales over its lifetime.
