there never was any confusion about Bitcoin Cash. it was always an altcoin and still is, simply because it never had any support from anyone. not miners, not businesses, not user, not nodes, not developers.

the same will be true about SegWit2x. look around and try to see how much support and from whom it has that support. it may not be clear right now but it will become clearer as we get closer to the date and we can see the support and where it is coming from.

and in the future whatever fork has the support of majority will be considered BITCOIN and everything else an altcoin.

what does Litecion have to do with any of this?
litecoin is a completely separate and stand alone altcoin with its own developers, own community and users,... it doesn't matter what happens with bitcoin different forks LTC will be LTC.
