re: 150m consoles?

Look at the PS2 sales curve, as the product evolves and becomes cheaper to produce, and hence cheaper to sell, more people buy it.

For the next 6 years, PS3 sales will ramp, and then plateau.

150m is a very achiveable target, especially when you consider it's likely to be the best and cheapest Blu-ray player for some time to come..

At the moment, PS3 is well ahead of the PS2 sales curve, and that sold ~130m to date, as more and more homes have tech goods, then more and more will turn onto PS3.
