GM goes bankrupt. Do prices of new Cadillac cars go down at the dealership?

Hey guys. I"ve been patiently waiting to buy my dream car. Cadillac CTS-V. I've been catching up on the news and it looks like GMs going to file bankruptcy. Should i wait to purchase the cts-v so prices go down, however the local creepy salesman is pressuring me to buy now because "Caddilac prices will stay as is even if GM goes under."
