Killing the Easter Bunny

My son loves Buzz Lightyear and has since he was 2. He has told us on more than one occasion that he wanted to grow up to be Buzz Lightyear. He has been Buzz for 3 of the last 4 Halloweens. My mother-in-law made him the most gorgeous and awsome Buzz outfit I have ever seen(when he bends his knees you see the knee joints). He still dresses up in it on a regular basis. He just turned 6 and for the first time in our kids lives, we are going to Disneyland. We have talked about it for 2 years and finally had the financial ability to do so. Our biggest motivation is so Ethan could meet Buzz. Sure my two daughters love the Disney Princess' but not to the extent that Ethan loves Buzz. So it was today as I was pouring his cereal and he was sitting there coloring yet another picture of Buzz(he is becoming quite good at it), and I said it looked really good and then I said, "Who knows, maybe someday you'll get to meet him." He looked me straight in the face and said, "Dad, Buzz isn't real."
The Easter bunny was dead. The cute 2 and 3 year old that wanted to be Buzz had accepted the truth that Buzz wasn't real. Have we waited too long to see his joyous face when he meets Buzz at Disneyland?? Did I blow that Kodak moment because I felt the kids were too little? Only time will tell, 2 weeks to be exact. I can tell he still loves him, just because he still draws him and still plays as if he is him but has the childish innocence of dreams been snuffed out? I'm hoping not. He still believes in Santa and the tooth fairy(he checks his teeth every day for a loose one) and the Easter Bunny. When he meets the under-paid sweating teenager stuck in an oversized suit will he laugh and smile and hug him and believe in Buzz again?
After he told me Buzz wasn't real I just gave him this look that said, "Don't be so sure." I know we are going to Disneyland, my wife knows but we haven't told the kids at all. We want it to be a surprise so I couldn't say anything. I guess I'm just crossing my fingers that somehow a part of his hope and innocence will be restored and I suppose in some ways...I'm hoping that some of mine will be too. It's too soon to kill the Easter bunny.
