The speculation over MSFP being delayed by the Visto lawsuit is fairly rampant, but I've found another gravevine that has a somewhat more believable excuse:
AKU2, which is the release you are discussing, has MAJOR memory leaks and is not what could be considered viable (and yes, I am using the release). Patches are being worked on, but I think anything you see in the next 2-4 weeks is unpatched and therefore likely to require frequent resetting (but hey, these are MS devices!)
Whatever the outcome, expect MSFP to delayed in USA significantly (as is anything mobile coming to USA since we're the third world of mobility) and even further if it is not solid. I do not think carriers have forgotten the need to pull HP 6315 off the shelf three times before a solid firmware was delivered.
