The next Lord John book

For those of you who have no interest in the furor over the Entrecard changes, here's a little tidbit I came across on Diana's blog the other day.
Somebody had asked her about the next Lord John book (LORD JOHN AND THE SCOTTISH PRISONER is the title, and we know very little beyond that -- except that presumably the Scottish prisoner is Jamie, at Helwater <g>). Here is Diana's reply:

With luck, I'll start work on SCOTTISH PRISONER sometime after ECHO is done. [g] No idea when it'll be finished/published, but _maybe_ late 2010 or early 2011. I won't have any idea how long it is until I'm well into it--nor yet how much ground it covers.

Now, obviously that date is not set in stone, and of course finishing ECHO is at the top of her priority list at the moment, but I think it's great that SCOTTISH PRISONER appears to be making its way up almost to the top of the pile.
Comments? Any other Lord John fans out there?

UPDATE 6/10/2011 12:36 pm:  Diana is currently in the final stages of writing LORD JOHN AND THE SCOTTISH PRISONER.  As of right now, we still don't have any information on a publication date, but it seems likely to be at least November, 2011, before we see SCOTTISH PRISONER in print.  Please watch the Release Dates FAQ page for the latest updates.  I will post here as soon as I hear anything definite.  Thanks!
