Hi,

Just to verify that I have seen this. I am sorry that I couldn't reply 
earlier computer breakdown, and vacations leading to backlog. I fully 
agree with Lars's response and doesn't really have anything to add.

I haven't seen any one claiming that they will take the pen on such an 
update yet.

Cheers
