Well I think that after final report is published it would be possible for lawyers to put a blame either on BA or Boeing or GE or any combination of them. Crew and maintenance issues (if any) goes to BA, the rest goes to manufacturers. And considering previous cases it is most likely that ALL of them will be blamed doesn't matter who's fault it was.
p.s. and to a furter extend if manufacturers are involved, FAA and EASA will likely to be sued as well.
p.p.s. just sitting next to my lawyer here
