Azure revolution - your opinion. (Valkyria Chronicles)

Actually, the announcement was made, the trailer was posted, now we can discuss it.
The trailer caused mixed feelings for me - on the one hand, it's good that the episode is alive and all that, but honestly, I would like to see other events. So I understood, it will be a spin-off that will take us some centuries back to the events that were nicknamed "Darcsen calamity".
What is your opinion?
