SDIO Support In CE 5.0 Dynamic insert/remove DMA (optional in standard host spec,platform dependent) SDIO interrupts Dynamic clock control Error recovery Wake-up Power will be handled using CE Power Manager Clients may be power-managed and tell the controller to put its slot into a different power state Multi-function and Combo devices Also support MMC v3.0 basic functionality In the next Windows Mobile release we're adding: Support MMC v4.0 basic functionality Performance enhancements for single block cards

The Secure In SD SDA SD Memory specification provides a mechanism to lock content to a specific machine We are not providing a block driver supporting it in 5.0 release explicitly. SDBus does allow you to build your own though Digital Rights Management(DRM)for all of CE is being supplied by a filesystem filter driver at a level above the SD Memory block driver
