Next New Frontier book delayed?

[Defcon]

I was browsing Amazon earlier today and I found this.

So far the next book is scheduled for June 2010, but this book is listed for January 2011.

Of course most of the time Amazon isn't the most reliable source - and shouldn't the next book be #18? - but I thought I post it here in case someone has more information. (Although with the current editorial situation I doubt it somewhat.)

Yeah, I found the same thing at Amazon.ca and Chapters.

They can't all be wrong. Dang. I was looking forward to a summer NF read.

Consider it a nice winter read.

and shouldn't the next book be #18?

Yes, but don't worry; there will be a 12-part comic miniseries to explain the discrepancy.
