RE: is Oracle really planning to desupport RBO?
In reality they cannot. Because the internal optimizer uses Rule occasionally, they must either remove this code from the kernel or perform a complete rewrite. In addition, Oracle, and its VARs, have several thousand tools that utilize rule based, for cost based is not as stable. Thank You Stephen P.

Re: is Oracle really planning to desupport RBO?
This is true for all new features from 7.1 and onwards. Apps 11i has been CBO'ed, so when recursive SQL statements are also CBO'ed I would assume there's only the rest of the world and their applications to worry about ;-).
