I would imagine that it's because of the European Union and how they managed to force Microsoft to strip IE out of their Windows-whatever install disks for their region and instead, provide an automated screen prompting the install for the browser of your choice after installation instead. If they integrated IE9 into SP1, the EU would be in another uproar over IE being forced onto consumers. So I suppose they figure its safer to just provide IE9 in another, separate update to avoid another litigation with the EU.
