He then alludes to the differences from the predictions made in "Back to the Future II" - such as no flying cars and the Cubs on the brink of being eliminated from the Playoffs, not winning the World Series in 5!

"Yes, it is different than we all thought," he adds. "But don't worry! It just means your future hasn't been written yet. No one's has. Your future is whatever you make it, so make it a good one."
