I am not going to speculate about litecoins future but a word of warning to anyone why didn't bother to listen to the feed linked above. Charlie Lee did not indicate that litecoin would be added anytime soon and actually insinuated that he believes most of the litecoin interest was in china and he suspected that most of that volume was false.
There appears to be a litecoin pump going on right now with the flurry of posts, some of which has incorrect information, so buyer beware. It may be wise to be prudent and make a decision about investing in litecoin once the pump is finished.
