New OWB Product Roadmap on OTN
I'm not sure how much significance we should attach to it (in terms of it being new news), but there's an updated product roadmap document for OWB now available on OTN. Apart from the details we all know about such as OBIEE support in the next release, ODI knowledge module support and so on, there's a fairly clear statement towards the end of the document that says that OWB and ODI will eventually merge:
"Short Term Strategy
Oracle purchased Sunopsis in October 2006 and re-branded it as Oracle Data Integrator (ODI). ODI’s mission is to enhance the Oracle Fusion Middleware offerings, which require broad support to heterogeneous sources and targets. Warehouse Builder’s mission continues to be to support the Oracle Database. Today, ODI and OWB are released separately. For the short term, both products will continue to deliver stand-alone releases. Although released independently, both products are currently being developed with a common goal of integrating with each other and, ultimately, merging into a single product. In the next release, for example, OWB will support the knowledge module framework developed by ODI. And in future releases, both products will share the same user interface framework and will be able to launch each other processes. Long Term Direction
Oracle is committed to protect the investments customers have made in both Oracle Warehouse Builder and Oracle Data Integrator. In a future release, Oracle will deliver a unified data integration product that protects customer investments in both products."
