Betrayed, no, that would be silly. Wii U is not a person, it's a product. Am I disappointed with the product if it has a shorter lifespan? Not really. I got plenty of value out of it - any game system provides incredible bang for buck compared to other entertainment options like drinks at a club, a concert or hockey game tickets. Heck, my Internet/cable bill is as much as a Wii U every month.
I'm excited for the reveal of NX, and there is a good chance I will pick one up if it looks good.
