I look at it like this:
The PS3 currently represents over 40% of the HD market. Even with current sales trends, PS3 isn't likely to slip below 33% of the HD userbase. If you're making an HD game, porting to PS3 would have to increase project cost by 50% before the price of porting to PS3 exceeds the increase in potential buyers of your product.
Granted, there's going to be some overlap of people who own both a 360 and a PS3, but I doubt that the cost of porting to the PS3 would increase cost anywhere near 50%.
