Assuming that people actually educate themselves (I know, a big if) I doubt it will go higher or if so not by much. Probably momentum still carries it for 2-3 months, but after that technology should win and bitcoin becomes a thing of the past giving place to the alt coins. With arbitrage, the futures should make it less volatile thus less exciting. Also futures let money pour into somewhere else, not directly into bitcoin.
The others should do a concentrated effort to educate the public about their existence. Most people still only know about bitcoin.
