Here is my understanding of the new Exadata announcements. Version 3 will ship with Oracle DB 11.2.x first and then will allow upgrade to Oracle 12C later. The current Exadata V2 customers can upgrade the Exadata software for the write back using the flash cache features. Half RACK Exadata V2 customers could opt for the other half with the Stony Bridge (Intel processors in the new hardware) and run the new Exadata software on the whole RACK and could also move to Oracle 12C.
