I'm 100% positive that FFG will be putting out expansions to fill in the gaps that will have the hero figures and the monster figures from the first edition. FFG doesn't overlook an opportunity like his.
Based on their history I would agree. Not owning the 1st edition though I would have liked to have seen the conversion kit be a separate product also, so the 2nd edition stand alone could have been cheaper. While I would be fine proxying 1E monsters and investigators. I would definitely not be interested in proxying paper map tiles as suggested. That being the case this release is still super exciting and I hope they continue these app supported releases going forward.
I honestly don't think it would have been any less expensive without the conversion kit. My guess is they wanted the price to be at $99.95 from the start. This is the price of Star Wars Rebellion and it seems to be where their big box games are headed.
I think the decision was whether or not to included the conversion kit in the box or to make it a separate purchase and decided to eat the cost of the conversion kit and put it in the box. This does two things for them. It garners a little good will from all the 1E owners who are going to complain about a second edition. The second thing it does is gives them a lot of flexibility on how to sell the monsters to customers that don't own anything from 1E or just own some of it. They just need to sell the plastic now. No cards, counters, tiles, everything is included already. I would think in the long run they will save a lot of money by not having to included this material in future monster/investigator expansions.
