There will be a bleedless verison and a bleed air verison GEnx. It's to early to tell as it's still in the design & testing stages.

The bleed air variant will also be used on the 747Adv.

Quoting HAWK21M (Thread starter):
Apart from the 5th Engine in the GE 90 family & lighter weight.

In the GE90 family? No. The GEnx will be lighter because they are their own family, utilizing some GE90 technology. If they were members of the GE90 family, would they not be designated GE90-67B, GE90-78A, etc? In fact (for the moment at least) they're designated GEnx-1A78 for the A350, GEnx-1B for the B787, and GEnx-2B67 for the B747-8.

With the GEnx? Never.

Currently, the highest rating is 75K. Even down the road I wouldn't expect anything over 78K.

Since most engines are designed to grow 15% beyond the launch maximum thrust, I would expect an 84k varient in a decade.
