Interestingly enough, someone on the 2000AD forums discovered that, according to Amazon, a hardback edition of the very first Case Files volume is being released in August later this year in celebration of a ten years of that series of books. The one particularly exciting piece of news is that, like the first Mek Files volume, this volume will see the colour spreads being restored and reprinted, and I presume it will also be slightly oversized like the Mek Files too. The less exciting news is that it's listed as a "special edition", which, taken together with the idea of it celebrating the series, implies that it's a one-off and not something to be continued. And yet I am hopeful, as it seems very strange that they'd only take the first book and reprint its colour spreads in a nicer edition instead of using such an opportunity to compile a "best of" sort of book. Hopefully we'll hear some more specific details soon. Although I'm sure those who have been buying the series wouldn't be too happy about double dipping, I personally would in a heart beat, especially for the early volumes.
EDIT: Here's the Amazon page by the way:

As I said on the forums, I wouldn't even mind if this were expanded to similar series' in the future if it does continue after this one volume.
