Of course, it's an important discussion point, but we don't know what unseen material Disney have of Fisher, there could be loads of unused footage for all we know...and yet, in post #3, we get "Abrams is going to screw this up", it's hard not to call that cynical.
Who said anything about a CGI character though? Abrams own words counteract this notion:
He says they won't use a CG character, but how else but through dubbing and/or CGI can they fill the blanks? Unless they propose that she just stands in the corner saying nothing, or by a miracle of chance the Episode IX script perfectly overlaps some convenient footage shot for Episode VII. It asks questions.
Now who knows, maybe the sum total of her appearance is simply to be killed off during the movie, instead of off-screen before the credits roll, but that still feels like a needless inclusion.
Declaring opinions as cynicism and misery isn't particularly friendly or improve discussion over something people obviously feel is a bad idea. Yes, wait n' see is all well and good but the news was announced she'd be in the film - it's hard not to discuss something intentionally disseminated for discussion
