Wow, that was quite the reveal trailer, does leave me with several questions.
1. How backwards compatible will it be as it is running on a Tegra, which isn't x86 like Nintendo's last two generations.
2. What is the battery life going to be like on mobile mode
3. How expensive is it going to bed.
4. Will it be 1080p at 60Hz or shoot to compete with 4k.
5. Will it be compatible with mobile cartridges such as the 3DS.
I suppose only time will tell as we get closer to when it comes out.
