I think we might see something coming up in the near future. Charlie Lee @satoshilite (twitter not steemit) has said that he knows his coin is a bit 'flat' at the moment but to hang tight as he will be implementing some interesting thing in the near future.
I might also add, in Canada they have just implemented 50 Litecoin ATM's which is a bit step forward for Litecoin. (They can also do Doge and Dash If my memory serves me correctly) But its a big step forward for Litecoin.
I hope litecoin surpasses bitcoin
Im not sure it will surpass bitcoin. But it might overtake for everyday use. It depends on what the supply and demand for these things are. A tell tale sign is bitcoin has 21million total cap. And litecoin is 84mil total cap. Which theoretically should lend itself to a 4:1 ratio. But it all depends on what kind of value people place on these things. That saying with th 4:1 ratio if BTC is 3415 USD then litecoin should be at 853 USD by current evaluation. Maybe its undervalued. Who knows. :)
It's not designed to surpass btc in per coin value, as @alhoppo says below 4:1 is expected value, it's supposed to be the silver to btc's gold. That said, I think it's more undervalued than btc.
