Gotta be honest, I don't quite understand the extreme negativity about the Switch right now. It's nothing amazing and I'm not gonna buy it at launch or anything but people are acting like it's the worst thing ever.
I'm not as negative about it as others, but the whole presentation was pretty disappointing. I loved the hybrid concept of the initial preview since I have a train commute but most of what I got during this presentation was a lot of waggle Wii stuff. They barely talked about the hybrid side.
On the price, I think $299 is an okay price, but the with the disappointing launch lineup through 2017, I think it just fed into the negativity. If it came out at $249, I think many people would have gone "ok, that lineup isn't great, but its $249 at least"
Also, the thin launch lineup brings back Wii U memories and with that system's history very fresh in minds, Nintendo should have done more to correct that. Even if they filled the slot with a lot of indie/Steam ports similar to the Vita it would have played better.
