First impressions... I'm pretty optimistic about this. And now I'm going to re-watch and note some things I like as I see them.
Name: Using a verb for a name...? It's not the end of the world but it just seems odd to me.
Home console: good. I'm curious about the way the dongle controllers (what should those be called?) 'dock' onto a controller frame with some kind of transmitter kinda like how the portable device itself has a dock, mainly because they show a more traditional style controller later on. Will it be like the WiiU where there's one 'primary' controller while the more traditional controllers are meant to be additions for multiple players?
For the dongle controllers... it would be really nice if I could play with them detached instead of hooked onto whatever that controller transmitter thing is. One of the things I liked about the Wii+nunchuck combination was that it allowed me to sit in any position I wanted. With normal controllers you have to keep your arms in a fixed spot which can be kinda awkward if you have a chair with arm rests or like keeping your arms close to your body.
The portable screen doesn't look too large, which should be nice. If it's much bigger than the 3dsXL then there's going to be problems. The detatchable controllers means you can keep them in another pocket without making the whole thing too big for one pocket. It also appears to have four shoulder buttons total which is an improvement over the 3ds.
When he gets to the hotel he puts the screen portion onto the dock with the controllers still attached, then uses the traditional controller I mentioned, so the first controller they showed with the transmitter thing in the center may be completely optional and only exist so that you don't need to buy a second controller if you don't want to...
I personally like the idea of using the dongle controllers as separate controllers for two/four different players. Reminds me of how in Mario Kart DS only one person needed to own the game in order to play with your friends locally.
I wonder if that transmitter controller thing doubles as a charger of some kind for the dongle controllers (Seriously what should we call these things)? It's likely not a motion/gyro sensor of some kind like I thought at first because they show someone about to play Splatoon with the traditional controller, and I heard that the motion controls in conjunction with analog sticks makes Splatoon actually playable.
Overall, I think Nintendo is on to something here. I may never take the thing out of its dock, but the option to do so is there, and it looks like they have a lot of functionality for their controls that makes them pretty versatile. It's not directly competing with mobile gaming because you can play at home with real controllers. If they can somehow also make this thing into a tablet of some kind then that could sell to a lot of people, similar to how people buy home consoles just to use as a blu-ray player, but I doubt that'll happen.
So... Monster Hunter, please?
