I don't expect the tenfold power increases to happen.

For one thing, I don't think it would be possible for stations to raise 
power to 500kw (or some other tenfold increase) near the Canadian and 
Mexican borders without major pattern changes.  Most Vancouver & 
Victoria stations, for example, are  10-20 kHz from Seattle area 
stations and would need to be afforded their current protection levels.

Add to that the economics of huge power increases.  Some stations like 
KJR and KRKO have boosted power to 50 kw, but it doesn't come cheaply.  
I would expect the jump from 50 to 500 kw to be rather pricey when you 
factor in the tower upgrades, new transmitter, new power feed, etc to 
handle the higher power, plus the higher electrical bill.  Would the 
increased  power outputs ever pay back through increased listenership, 
if the station could actually afford to make the upgrade?  I can see a 
chaotic situation developing where stations that don't boost power lose 
coverage because of neighboring stations that do.

Not to mention the impact on people who live near transmitter sites, and 
concerns (real or imagined) about r.f. exposure and effects on 
electronic devices in their homes.
