I can understand their reasons but i think this will be a big mistake, the witcher is a great game but is laking endgame wise. the only thing players can do is start the game again, as someone said a lot less people will care about the redkit if it will be released a year or a year and a half after game launch.
Hope that the reds will surprise us and release the redkit earlier. even 6 months after release is ok
Redkit1 was a very hard program to use but it was manageable, but it was possible to create interesting quests there. but if you will search for adventures you will see very few. I think that one of the reasons was that redkit1 was released so far down the line.
