I e-mailed Frantisek about this and here's what he wrote back
"From first book I will use about 20 –30 photos …. New issue will included all details, which was in 2005 possible publish as censored secrets (interior, electronic boxes, turret power etc.
About 40% will be on SURN radar vehicles, which not was in first issue.
You can wait on preview pages on my web before publishing."
