Yes, it is true. The 20GB HDD model for the PS3 has discontinued. Meaning that SONY has stopped making them. On the plus side though, SONY is now working on the 80GB HDD. Hoping that it will be more successful than the 20GB HDD was.

SONY is thinking of making the 80GB HDD a silver colour console, making it more noticeable between the 60GB and the 80GB. Looks like we are getting more than what was expected from SONY.
