The sentence is "Here's what's waiting for you in the next two weeks". If they turned some of it now, that would still be valid. All it says that within next two weeks some of those things will be around. It has no indication of how long.
Now, if the sentence said "Here's what's waiting for you for the next two weeks", then it would be stronger case that those things should last entire two weeks, because "for" is stronger than "in". Still, even then, not invalid statement if some of them turned off.
Don't take me wrong, I want to see all of the events last two weeks, and I hope they do. But I am not going to read what I want to read instead of what is written.
