Future Big Data Concept getting applied to Oracle Products

Everyone is talking about Big Data and how it's going to transform Data Warehousing.  What I'm wondering is when is Oracle going to make Oracle BI products work across multiple servers and use multiple CPUs and RAM?  I would expect within the next 5 years Oracle DB, Essbase, OBIEE, etc, to be re-written to take advantage of increased abilities and as a result, increased performance.  What do you think?
