The initial date for the BES upgrade was November and then moved back to mid-February. It has since been removed from the Life Cycle portal, so it's status is currently in limbo. The latest beta OS versions we have are still OS 4.3.1. If there is a delay, it's fairly last minute and should not hold up release more than a month or so, in my opinion. If the delay ends up being fairly big, I wouldn't doubt it's release in the Asian market followed up by a few more rounds of QA and possibly an April release. It'll be out before May, unlike BES 5.0 (which was initially slated for a May 2008 release, per RIM's announcements last year at WES ...it's currently in pre-beta and has slipped no less than 6 months, possibly 9-12 months).
I hope that your assessment is correct, although coming from a past of working in Engineering, dates always slip and therefore, my guestimate was May...but believe you me, I hope that you are right and I am happlily surprised.
thanks for the response
