I am not interested in short-lived one-time colabs on stage, so I spare you my commentary. For lives consisting of several groups (Two Man, Three Man) I would prefer more priority on groups with similar style. So Passpo / Silent Siren, Babyraids and the like. It still feels stange to go for a Three Man like the one with Bellring Girls Heart - Moso Calibration - Rhymeberry (+OA Maison Book Girl) in it's line-up, all of them completely different. There are already enough festivals that present a wide range of diversity.
The region-coding on Youtube isn't that much of a problem now, as there are Add-Ins to bypass them easily - not on mobile though, I give you that. But in comparison posting a comment on LINEblog via VPN is much more difficult. DVD are no problem for me as Europe and Japan share the region code, but I agree that this shouldn't be the case. Region coding was invented for the reason to prevent sales of oversea editions. Obviously neglectable in the case of Japanese Idols, that have no market / production outside Japan borders. Despite that I also fear Blu-Rays would be released with Region Code.
Anyway, I have no specific knowledge on Japanese record companies. I just hope it will be one that handles Idols better, like marketing, Music Videos, more high quality. Without disregarding the fan interaction, like PCI or H!P *grumble*
