GE90-110B1 Still In The Plans?

I guess this is pretty much a Hamlet question... but anyone who's in-the-know, please chime in!

Question: the 772LR was initially advertised as to be operated solely using the GE90-110B1. Ever since the performance improvement announced for the 777NG family, the GE90-115B has been advertised as the engine for both the 772LR and 773ER variants.

Is the GE90-110B1 still in the works? It does however seem like it'd be less expensive and quicker to just certify the -115B on both aircraft, instead of creating a derated version of the same mass.

Anyone?

This article sums it up pretty well:

" Following an extensive technical evaluation, GE Aircraft Engines was specified by The Boeing Company to develop a 115,000 pound-thrust GE90 derivative engine for all longer-range 777-200LR and -300ER derivatives"
