Most of the other alt-coins are declining in price right now. BTC and LTC are holding up pretty well and have stayed pretty flat today... Namecoin and Peercoin are not doing so hot...
The fault of new alt-coins Drk, Xc,Nxt etc which brings new features and are more hyped.
LTC is being kept alive by a massive bid wall on btc/ltc chart. Furthermore ASIC for scrypt is adding constant selling pressure to recoup their mining hardware investment.
