Rolls-Royce's new BR700NG engine project - airframe?

[Hodd]

Rolls-Royce's BR710/715 has been in service with Bombardier and Gulfstream for nearly two decades, and the BR725 is due to enter service with Gulfstream soon.

RR are also developing a BR700NG, which I believe is based on the BR710.

Does this new engine have an airframe customer? There's no mention on Google, RR website or anywhere.

I have heard a rumour that Gulfstream will have the rights to this engine and as a result the global 7000/8000 when released will be fitted with GE motors

One more (unsubstantiated) thought after talking with some factory guys this week: "BR700" refers to the entire engine series, so the BR700NG would simply refer to the next generation of engines, not a specific engine that (for example) might be for the next generation G450/G550....
