The following may appear in the upcoming release Oracle 12c database.
Architecture in 12c: Multitenant Database , container CDB.
Indexing in 12c: Allows multiple index on same column definition , appealing but not confirmed yet.
Partitioning in 12c: Online move of partition, multiple partition merge in one go, partial indexing, interval reference partitioning
Identity columns in 12c: Attached to primary keys and auto incremented as it grows.
Archive Log Compression: Yes, it appears in metalink, Archive log compression with “ALTER DATABASE ARCHIVELOG COMPRESS enable;"
I Will keep adding as and when I see/heard something new from others or documentation.
