Bottom line I will change my water pump on my BMW at 100K if it had not already failed because you are asking to get towed if you don't so why gamble and get stuck somewhere in the middle of no where usually at the worst possible place. I consider water pump replacements at 100K part of the cost of owning a high mileage car.
I did the same thing for my wife's Honda Odyssey - changed the thermostat at the same time as the timing belt.

Although if I keep my 328xi until 100K, I am looking at a pretty hefty bill to replace the water pump, thermostat, trans and differential fluids.
