And everyone else is going to the V-22 platform instead?

Nope, you don't have the plot at all here.

The V-22 is not in the same lift class as the CH-47 or CH-53E. It's a
medium-lift platform, not a heavy.

The only buyers on V-22 are the Marines (replacing CH-46s) and Air Force
Special Operations Command (replacing MH-53s, which are smaller twin-engine
versions of the H-53, not the bigger three-engine CH-53E version the Marines
fly).

Right now there is no final plan to replace any of the heavy lift helos in
any of the services.
