I know some people get sensitive about it, so SPOILER ALERT for a comic book story printed in 1981...
While replying to a reply to a comment I had made, I did a search for an image of the comic panel from the X-Men: Days of Future Past story, particularly the scene where in the "future" Wolverine gets fried by a Sentinel when his and Colossus' fast ball special turns out to not be fast enough. And that's when I noticed the year is mentioned as 2013!

Which means the "Days of Future Past" really are almost in the past. I've been looking forward to seeing how 2015 looks in 2 years compared to how it was depicted in Back to the Future 2, but didn't realize this X-Men future should be happening now. Just thought I'd mention it in case anyone else didn't notice either.
