I think their internal data is showing that people prefer larger screens + don't mind larger portables. I mean people take their huge phones and even tablets everywhere. Looks like they went with a significantly larger system. I think their internal data probably also showed people weren't shoving their Switch into their pant pockets (like a DS or 3DS) anyway. It's too big as is, so I think they figured they can go even larger if you're putting it in a bag, case, or larger jacket pocket or something. 

Another plus though beyond the chipset, screen, and battery stuff is the Joycons are going to be larger too which should help comfort in using them especially when held horizontally.

Yeah, the joy cons could do with being bigger, gotta wonder will they pull a PS portable like thing where they are bigger than the tablet but without the back panel. It'd look funky but since it's going to be chunky anyway why not go the full hog and have couch level comfort.  

They will probably size them up too because it's a very obvious way of getting people to have to buy all their Joycons over again, they can claim "hey the system is larger, we have no choice but to go with larger Joycons!" instead of reusing the same size and letting people just use their existing Joycons attached to the system. 

Extra Joycon sales are probably a huge cash cow. 

I wonder if Nintendo will opt for a 120 hz screen. That would be quite nice.

Not a chance 

120 hz really that expensive?  I don't follow portables but on TVs is is fairly common.  

I would assume so, the models with 120 are dramatically more expensive than 60hz TV's. At least in my experience. Some have Ai integrated that claim 120 but aren't really getting there. 

For sure and they'll probably still have joycon drift as a feature as to that fact.
