It was a total bait and switch. They showed something that got people excited then said, "Nope, psych." That's the very definition of a bait and switch. Tech demo or not, when you show something like that, you're inciting expectations. It's not like Nintendo was blatantly like "Check out this graphical demonstration but be forewarned, the next Zelda game will look nothing like this so if you're expecting more of this, you will be sorely disappointed and it'll be you're own fault." I, personally, didn't hate the cel-shading. I just thought Link's character design was stupid, but I got over it. What I didn't get over was how boring everything not involving dungeons was in Wind Waker. God, I hated sailing. That got old really fast....
