If are talking about the Pay channels on B3 then apart from the some testing there is no indication that Irdeto2 will be used at all. Foxtel have just announced they will be using NDS's VideoGuard system and as for Austar, well they don't have money to burn..
While it seems Irdeto 1 and 2 can co-exist in the same datastream, any provider that has switched to the later system has done so quickly, turning off the Irdeto1 signal sooner, rather than later.
