Will GM release an ECU upgrade to boost horsepower considerably?

The rumor mill says that GM will release an "upgrade" shortly after the Cobalt SS hits the streets in large numbers that will significantly increase the stock horsepower output.

Some are claiming a 35hp to 70hp increase (mostly achieved by raising the boost)

What does everyone else think?
