The "Poor" battery life which hasn't detailed will likely be simialr to the PSVIta. I've yet to see the Vita's battery life be brought up in debate over why it was failure, I doubt it would have much impact on NX's success unless it was ridiculously short. Where size is concerned a 6" screen is all the info we have and 6" fits on the top half of the 3DS XL's clamshell. If it was a major concern Nintendo could go for a traditional clamshell design instead a tablet/psvita design where the controls sit on the side of the screen. The home console will be a quality Nintendo box, by subpar you must mean it'll be weaker than PS4? So many people who want a core home console will already have a PS4/X1 or will be eyeing one up since the systems have been out for 3 years and have 100s of games out on them already, 3 years of highly established marketing, online connectivity with friends is obviously important for the CODS/Fifa/Titanfall's/Star Wars' etc. Coming in mid-gen and trying to tackle this audience simply not realistic.

Also Nintendo primarily makes their money from selling full games on their handheld consoles, anything less they can do on mobile as show by pokemon go and upcoming Mario go. Nintendo handhelds are always bigger then their consoles, always. It cannot be an after thought. Their last 4 home consoles, were outsold by the compeition by at least 3:1. The home console is least important thing in Nintendo's future.

Thats equally the NX's problem. Hell its even the PC's problem (look at Witcher 3's downgrade). Games are being built primarily for the PS4/Xbox One (60m users and counting). The only place the NX can excel is framerate, anything else, if you see it in the NX build of the game we'll likely see it in PS4 Pro's.

whether or not NX gets them unless there is a PS4P version isn't as important. As long as they get the games in any aspect will be a victory. More than likely, the only ones who will be taking full advantage of NX will be Nintendo. But at the very least, for the first time in a decade, Nintendo will still be in the conversation when it comes to 3rd party.

The home console is the most important thing in Nintendo‘s future as mobile devices further erode away the remaining dedicated hand held gaming market. Sony knows this. Thats why they will not make a replacement for the Vita. Nintendo knows this as well.

I just had a idea based on this rumor. What if for the portable option its a controller that has a processer that clips onto your smartphone with an adjust as ble clip. You just instsll an app to start the system or use bluetoith connectivity or something. But... that might be too complex for the average consumer

This still requires the third party games to sell. if the same Wii U audience that allowed COD & Assassins Creed flop are the NX's primary early adopters then third party success is far frome gaurnteed. 

I was speaking in terms of exclusives for the platforms, Pros added power doesn't help it compete because of the basic model NX mean while doesn;t have that issue.

Considering the fact that the WiiU has lost more than 85% of its original userbase compared with the 44% of the 3DS, Nintendo knows they can't put all their eggs in two baskets anymore. And if they have to choose, they'll chose handhelds. Even now, it's the thing that is giving them profits, compared to the money hole of the WiiU.

Well how easy the games are to port will be a big factor. Ubisoft is singing the praises so I have to assume that it isn't near as bad as Wii U. At the very least, they will be able to get those ps4 games.

They have a monopoly on that dedicated handheld market so even as it erodes, it gaurntees them more sales then what we're seeing with Microsoft and the Xbox One. Sony has an undeniably dominant grip on the console market, Nintendo will not put their financial success of the next 5 years in the hand of traditional console versus a handheld. They're simply not at a point where they can pretend that their handheld isn't the sole reason they've been relevant the last few years.
