>>48818874ILCA will probably be doing all remakes from now on. The franchise switching from handheld-based to console-based now means the dev time is too much for Gamefreak to make multiple mainline games AND remakes every gen.
That said, BDSP being ILCA’s first ever actual game, I reckon they half-assed it in some ways and weren’t given as much time as was ideal. GF probably realised late on they couldn’t make Legends and DP remakes at the same time, so outsourced them at short notice. For BW remakes ILCA will probably start work on them round about the same time GF does on Gen 9.
