Illustrations etc are still in Kindle versions. Not sure the old versions had them though I think they are part of the new ones only.
Here's his blog on the re-issues

Hes been re-releasing them this year so make sure you get the latest versions with new illustrations, not sure if the content has been re-written at all.
First 3 have been re-done and book 4 will be out a bit later this year before the final book is out.
Not read them yet waiting for the final...
