BD-Rom?

[EQ3282]

Curious about this:

When does everyone think BD-Rom will enter the market, and how long will it take to usurp CD/DVD-Rom?

I know some computers are being made with BD drives, but I'd say the number of non-custom models with the BD drive is less than 1 in 10 at this point. So, I assume BD has to gain momentum some, but I think its only a matter of time til the higher capacities of BDs take over in the computer world too.
