Call of Cthulhu Investigators Handbook (Call of Cthulhu Roleplaying)

A collection of rules, updating the worlds greatest role playing game. New rules, new additions, more streamlining, it looks like it will be better than ever. I'm sure that the extra maths in creating investigators probably ends up creating better,more rounded characters to play. Enjoyable to read, with only one slight complaint. No mention of other eras other than modern or 1920's. Does this mean that there will be a seventh edition Gaslight rules? ( )
