All the infrastructure is in place to make it a major coin. Peercoin for example has a 100+ million market cap, but only 550 tera hash to secure its network. Compare that with iXcoin with 10,200 tera hash. Also, I don't see any new PeerCoin innovation, their client is still back on version 0.6 or something.
PeerCoin doesn't really need hashes to secure the network, it's secured by other means.
