I believe to revoke a certificate Verizon/CyberTrust would have to issue a revocation cert and then send that to the browser vendors. The browsers would be patched with the new revocation cert, and would reject any certificate chain that included the (now revoked) Etilsalat cert. Even if Etilsalat generates wildcard certs right now, they will be signed using Etilsalat as the issuer, and so will contain the revoked cert in the certificate chain.
