BCH yes, btc/w segwit no, but not really either. BCH won't obsolete Litecoin, it will just be the "Silver" to BCH's gold instead of BTC's gold. One for moving around large amounts, one for buying small things like coffee. I would still rather buy my coffee in litecoin (1 cup of coffee cost ~0.05-0.1 litecoin for a $2.5-$5 cup of coffee is reasonable)
