VMWare to acquire SpringSource

I found myself doing a double-take as I skimread the Twitter feeds this evening. VMWare to acquire SpringSource - hey, hey what the?

Rod Johnson has blogged about it, and this time it's not April fools day so there may be some truth behind it.

I wonder what this means for other virtualisation and cloud computing providers?

For instance, will this influence the direction of Grails support for Google App Engine? After all, it didn't take long for Grails to do an about turn and support Tomcat instead of Jetty as its default servlet engine after G2One was acquired by SpringSource.
