There are just too many unknowns right now that make this impossible to predict. CU is in a prime position to keep Coach Boyle if they want to. If he proves out over the next couple of years, the AD should give him a big contract that reflects his success and their desire to retain him. If he's doing that well, then additional investments in the basketball program would probably be warranted, which would go even further to keeping him. If you've a top 4 team in a top 4 conference, I really wouldn't see him jumping ship unless it is for a number 1 team (UNC, Kentucky, UCONN, KU, etc.) and those jobs just don't open up very often. If he builds a winner, it is up to CU to make sure he wants to stay.
If he does well enough to justify an offer from one of the programs you mention then he will have won enough here that we will be happy anyways and have some quality options interesting in replacing him.
