Nobody knows = there is wide disagreement

My personal feeling is that I can eat like a king every day of the week. If I only had access to one kind of dessert, I'd be fine. I'd get tired of it. Oh, vanilla ice cream again.

But we have access to a wide variety of highly palatable foods, each with distinct flavor profiles; and advertisements reminds us how much better we'll feel after a snack!

I always take "Nobody knows!" "Nobody could have predicted!" as a warning for either something really dumb, biased, or uneducated take is about to follow.
