1) How long does the battery last in the tablet when gaming with it
It isn't known yet. More details will be revealed closer to release.
2) What happens to the whole console if you damage the tablet portion, is the whole thing then cactus. Seems so, given Nintendo said the main HW is in the tablet bit and the dock is primarily for connectivity
You're right, but that should be a given. Also, Nintendo consoles are tough as bricks - the 3DS can survive 30 foot drops with only scratches.
3) Is there a 3DS successor planned , if so , how will the switch effect sales of it. Or is the switch meant as a console and 3DS replacement
As it seems right now, this isn't Nintendo's next-gen handheld. With their current partnerships, it's possible they'll move either consolidate some of their handheld divisions into the Switch, and some will develop games and accessories for smartphones (as done with the partnership with Apple).
4) When you remove the controller portions from the tablet, like in the ad when he is on the plane. Unless you also carry the central controller connector, the controller must be used as two halfs. Needing a central connector for the controller IMO is kind of crap, it affects portability by needing to carry it around. More importantly , its a pain in the ass to have to dig it out of your bag and setup the controller.
It probably won't be necessary. The centerpiece is more comfortable, granted, but anyone who has used the Wiimote + Nunchuck can tell you that that control scheme is totally viable.
5) The more I think about this, the less Im feeling for it. Look at the dpad, or should I say lack of, it's just 4 game buttons . I can see why they did this (so both sides of the controller are equal and be used by two players), but it's still bad.
I don't really agree, seeing that even 2D platformers use the analogs nowadays over the d-pad (Guacamelee! comes to mind), and while I do like playing with the d-pad, it's not a central feature anymore. Especially if Nintendo doesn't fuck up and brings back the GameCube analogs, with their hexagonal edges that let you execute PERFECT diagonals, horizontals and verticals.
6) Apparently the pro controller will have a proper dpad from what i've heard, if so, not sure how devs would deal with the difference . Are they really going to develop a game that works better with a controller that's optional - by that I mean, make use of diagonal movement which is achievable on the pro controller and not the standard.
Again, not an issue if you use the analogs as the main way to control your character. The d-pad is relegated to secondary control structures, quickswitch and button replacement nowadays. This is especially true when you separate the two Joy Cons and use one of them horizontally - the analog stick is your d-pad in this weird SNES controller.
How is that innovative.
1. It lets you play current-gen console games on the go.
2. It lets you play console games without a TV.
3. It has built-in support for multiplayer WITHOUT any added accessories.
4. It uses an nVidia GPU in a console.
5. For Nintendo, the control scheme is actually sane for the first time since the GameCube.
6. Multiplayer will have more simplistic, SNES-like controls, while the singleplayer will have a full control scheme - letting even less experienced players enjoy the game without having all of its complexity, without actually handicapping the core experience. (This is ingenious, if it actually works)
7. It isn't the GPD Win and screws over IGG backers.
EDIT: By the way, if anyone wonders why am I supporting it so much aside from just being hyped, it's because of the recent failures of Nintendo - the Wii which failed hardcore gamers, and the Wii U. Both of those failed because they were too esoteric and weak to develop games for, and now Nintendo turns around and develops something that's both innovative and has all the right conservative aspects at the same time.
But still, it is haunted by the reputation of the past systems, leading to videos like this:https://www.youtube.com/watch?v=9SaQ9kJV8w0
Which say "Nintendo lied!" when they promised 3rd party support, which is not only out of their control, the supposed games they promised were by studios that went bankrupt midway through development (Metro: Last Light, 4A Games) or by publishers powerful enough to do whatever they wanted, and they didn't want to develop for a system with a smaller audience (Ubisoft and EA, for example).
So I'm going to support this until it's released and then it can prove itself to be worth it. That way we have a good chance to get a system that isn't filled with shovelware (Wii) or is barren (Wii U), and that is actually good on its own right too.
