KPMG & Deloitte is the new auditor for the satyam,
The pricewaterhousecooper is the former auditor and blamed for this billion dollar satyam scadal.
The investigation agencies are sweeping the accounts maintained by the pWC and can proceed a legal actions on them.
So the satyam new board replaced the auditors in order to regain the investors confidence.
I hope this is a Wise move.
