How long til Blu-rays get phased out

Basically just the title. With DVDs getting tossed to the wind it made me wonder when will blu-rays go? I'm gonna miss bloopers and extra scenes

Edit: A bit confused but the general consensus is that in some areas BRs have already began to be phased out while in others they're just trucking along perfectly fine. It'll be that way until they stop being profitable to the studios who make them. Is that correct? I don't think the 8k argument is valid imo since that's really niche currently.
