Is it okay for me to feel very let down?

I've been pumped for No Man's Sky ever since it was announced back in 2013. I've thoroughly absorbed every morsel of news about the game that I possibly could. So, when the AMA was announced, I thought that we would get a release date for sure. To be frank, I don't care about the littel details of the galaxy anymore. I'd prefer for the cool features to be a surprise. Anyway, 12pm rolled around and I instantly read all of it, only to read an excuse as to why I didn't know the release date yet. I don't care when the game comes out, I just want a timeframe! But I don't think Sean should have said at E3 that he would announcd it very soon. But I feel that those who complain on this subreddit are justified in their actions since we've been teased so much. Am I alone on this?
