Jason Mark on his website has stated the following:

"In other news, we have authorised Stackpole Books to re-issue “Island of Fire”. We must receive at least 2 or 3 emails a week enquiring about this long out-of-print book. For all those that have been asking, you won’t have much longer to wait. When it becomes available, we will be offering this book to our customers, so if you want to get a copy from us (signed bookplates will also be available), get your name on our list by sending an email"

Well if it is a Stackpole Publication, be warned, it will most likely be a "Perfect Binding" job ( the most imperfect means of binding a book ever devised). No better than a toilet roll at worst.....
Look for a Leaping Horseman edition if possible...
