Maybe I missed it somewhere, but I was wondering if its been mentioned what generation of eMMC is in the bionic.

It gets called External Storage but the name is misleading

From I forget where - "Traditionally this is an SD card, but it may also be implemented as built-in storage in a device that is distinct from the protected internal storage and can be mounted as a filesystem on a computer."

Currently it ("External Storage") is only in the Photon, the Droid 3, and the Canadian GSM Droid 3

Some background here: Powered by Google Docs

Breifly:

emmc 4.5 (new in june? 2011) features interface bandwidth increase from 104 Mbyte/sec to 200 MByte/sec
enhanced partition attributes for system code and temporary data and separate data removal mechanisms

emmc 4.41 features high priority interrupt mechanism (HPI) and host-controlled background operations processing (BO)

Apart from being relevant to booting, one neat thing the newer generations can do is execute code in the eMMC itself without involving RAM at all. Possibly adding a layer of complexity to the bootloader, or ( crosses fingers ) a hypervisor.

Yes, I'm still hoping for a baremetal hypervisor in the bionic:)
