i think that is an april fool joke, check bitcoin board they are also signaling for segwit, and guess what today is 1 april, sound strange? not to me and also why litecoin need segwit, it has 2.5 block times, which help already have 4x the block size of bitcoin, with is no where near to be full with current volume of transaction, this voluem is a joke when you compare to bitcoin daily transaction volume
