Nokia N91 includes MMC slot?

I heard a rumor, that the long announced Nokia N91 will include a MMC slot in addition to its 4GB hard drive, too. As much as I like MMCs, but right now Nokia uses MMCs, RS-MMCs and microSD slots in its various mobile phones. I wonder why they don´t just use normal SD slots for all their devices. It would make life so much simpler for their users, not to mention the huge cost savings when buying flash memory for your Nokia device. Update: in the meantime I found out, that this was just a rumor. The Nokia N91 won´t include any flash card slot, only the built in hard drive. Sorry for generating any confusion.
