Do you think any of their young forwards will make it at least as squad players in the next few years? Batista Meier, Tillman, Zirkzee, Arp...can any of them take some of the minutes vacating from Lewandowski, Muller, Choupo-Mouting?
OBM & Arp will need to breakthrough elsewhere if they can still reach the necessary level to play for Bayern. Zirkzee OTOH I can absolutely see replacing ECMC if he continues to progress like he has been...at least if they can't make a move for a more exciting prospect like Sesko/Hlozek.
Tillman is a wildcard and I have no idea what to expect from him. Though I've only ever seen him play in the front 4 for club or country, he was an 8 at previous levels who got pushed forward because of injuries to Bayern's youth strikers. With his skills & physical tools, he's really interesting...probably the most interesting of that tier with Nmecha / Beier / Krüger atm...but I'm not sure he's ready to go straight into Bayern's senior team. Hell, I'm not even sure that his future lies in the attack rather than becoming a Goretzka-esque box-to-boxer again.
In general, I feel like kids either get regular cameos with Bayern's senior team & impress, like Musiala last year & Nianzou this year, or they have to leave & make their breakthrough somewhere else. So I'm probably hoping for Rhein, Arrey Mbi & Tillman all to leave Bayern in the summer, unless they start getting regular cameos & are poised to crack the rotation for next year.
