is ps3 actually selling better than 360?

[Tachikoma]

The real rate is most likely between 38 and 43% for pre-S models and 3 - 11% for S model.

Just as is the case with PS2 and PS3, a drive dying or HANA/ANA chips dying, or any other related issue beyond RROD is counted as a failure and accountable to the overall failure rate.
