I am not sure, and I have never said that I was. I am reporting what I have heard several times from BA sources. I think you'll find that WeAreFlyingHigh is the one that is sure of their prediction so why don't you address the point to him/her and ask what they are basing their certainty on?

As you are BA staff if would be interesting to know if you are aware of any suggestion anymore would be ordered and if so roughly how many?

Of course things could change and a few more could be ordered in the short or medium term. If some more are ordered I wouldn't expect it would be too many though, again could be wrong.
