Well im just gessing because somebody said there will be an announcement in the next 2 weeks and 2 weeks has gone by. Simple.
These things take time, judging by the last couple of pages on here, attention may have been turned to the incident at MAN last week etc...
Id say that we could be waiting untill the begining of November to hear any announcement. Remember the two weeks time frame was just a rumour, as is the location of the next base at the moment.
