Some have said that Litecoin getting onto gox would be big for it. There's supposed to be a new US based exchange coming online shortly, coinMKT.com, that will be exchanging BTC, LTC and several other cryptocurrencies. If this exchange ends up being well put together, it could have a similar effect on price as the increased liquidity could help drive the LTC price up.
Coin Market is live, and yes, LTC / USD is one of our main pairs. Try it!
