OBIEE future roadmap - Rittman link

This i a good article talking about how the architecture will evolve in OBIEE... this is from Mark Rittman and not Oracle.

The SOA is the key concept in my view - will this be accepted by the industry for data warehouse dealing with Peta bytes of data???

QlickView

This is a desktop analytical product which is visually appealing (Ajax) and easy to use. Rittman wrote a good article comparing this with Oracle's Essbase http://www.rittmanmead.com/2009/08/15/a-quik-look-at-qlikview/

Key Highlights
1. It is meant for desktop.
2. It does in memory computation. It compresses data so a 1 GB essbase database is 4 MB in qlickview.
3. Visualization is intuitive and allows user to dig into areas which he/she wants to.

So, which BI tool will this get integrated with in the future?
