Hello BOLK!
I think you might be interested in reading some old posts in the Royalty of Brunei threads because there have been talk about the marriage between Prince Qawi (the son of Prince Mohamed) and Princess Majeedah... People have been talking about it in Brunei right about the same time they were talking about the Crown Prince and then Dk Sarah. But the reason there hasn't been any early big announcements is because this would just be a wedding between royal family members... As oppose to CP Billah and Sarah... because at that time, there were a lot of speculation about who the girl is and CP Billah liked another girl who was not quite approved by his parents! And when, I guess, all these people talking about it around the country became too much, they had to announce the wedding early! Just to ,how to say it, uphold the dignity of the royal family... them being malay,muslims too... its quite indecent to hear all the many versions of the Crown Prince's "quest for a bride". I'm sure that you as a malaysian understand what I'm trying to say...But yea coming back to your question, we'll just wait for the official announcement about Prince Qawi and Princess Majeedah. And also, i've heard that this wedding was supposed to be sooner but they had to postpone it a bit because Prince Qawi's mum, PAIPA Zariah was ill for a while. I'll let some other members answer this question too, there may be others who know better!
P/S: I think it'd be to my comfort to let you know that I'm a "she" hehehe... "Dang" is short for "Dayang" which is the Bruneian word for "miss". And Dang Ayah is a name of a long forgotten Bruneian royalty who lived long ago... she was buried alive because she ran off with a commoner she fancied... hehehe but its not my real name though! Cheers!
