Heads up
A possibility for the current (over)use of the term may have something to do with the preoccupation with military activity. Another common military term is HUD, the acronym for heads-up display. In aircraft, this is a projection of instrumentation readings, target acquisition information etc. onto the canopy, so the pilot doesn't have to look down during close quarter flights.

Re: Heads up
I was in a conversation today with a gentlemen nearing his 100th birthday. I used the phrase "heads-up" to mean "give him fair warning" and he made this comment. He said that his father used it and it came from the trenches in WWI. If you were not paying attention you might forget and put your head up. Which then made you a standing target.
So heads up was a sort of early warning of potential (personal) disaster, and advice to put your head down.

Re: Heads up
The most plausible explanation I can think of is that the expression arose in the context of some person in authority directing a roomful of pupils or office workers to stop what they were doing and pay attention to the speaker with an instruction having the format, "Heads up: [Content of message / further instructions]". The transition from this scenario to the general usage of "heads up" to mean "I'm about to tell you something I think you should know" would be an easy one.
However, this is just a guess.

Re: Heads up
Stagehands shout "HEADS!" when someone drops a hammer (or anything) from the catwalk (a grid way up high in the "fly space" above the stage). They also shout it when a piece of scenery starts to teeter, or if anything dangerous happens -- especially from above. "HEADS!" means immediately cover your head and brace yourself for possible disaster. The longer version would be "heads up!", but brevity is key in these cases, I guess.

Re: Heads up
.. interesting Shelley that when I was still playing Rugby we would, at training, call heads!! in the same manner as you describe .. however it meant in our case that somebody had kicked, or thrown, a football which stood the chance of hitting unaware players on the head ..
