Actually it sounds like something that they would normally release at WES (in two weeks) but they announced it today (with full coverage in the Wall St. Journal) to deflect criticism about their outage last week.
Pure speculation on my part. I've asked Oliver Stone to investigate.
Apparantly RIM has a higher opinion of the WM platform than do some of its biggest fans. Personally I like them both. BB's are great but my 8125, Blackjack and Mpx220 are all way cooler than my 8700c, even with the Optus 4.2!!!!
