Portal 2 Leaked Endings Causing people to Cancel Preorders?

I was reading on the forums at Steampowered.com and I saw a thread with a person saying that the endings were 'spoiled for him.' I, fortunately, didn't actually watch the ending videos I posted before I put them up - with the exception of the Portal 2 End song. I really am glad that I didn't, too! I don't want to end up like this guy, regretting having watched the ending at all...

I'm sorry if I've spoiled the ending for anyone, but I had to post them in case someone wanted to see the endings. I'm sure the endings will be all over YouTube in a few days, anyway; I was just able to get them early, before they were made Private on YouTube.

I will be posting one more blog post later, after the announcement in LESS THAN FIVE HOURS!
