SAP just announced that their High performance ANalytical Appliance (HANA) is now available.  HANA supports both the SQL and MDX query languages.  SQL is supported via ODBC.  I am not sure if they also support JDBC, but if not, it would make sense this would come very soon.  MDX is supported via ODBO.  XMLA is not supported yet but most BI applications and especially Excel are more ODBO-centric so this is fine.  Since Excel only works with ODBO providers, I would much rather have ODBO than XMLA.

Some comments about HANA from Jake Klein (VP Product Management at SAP): http://sapteched.news-sap.com/2010/12/01/still-wondering-what-are-in-memory-and-sap-hana/.
