I got some friends which got out of DRK just now, they are not leaving because of the name change.
They got the oppinion that BTC is topping around 300 $, and so they get rid of theire alts, and also of the BTC before BTC drops (what they think it'll do).
From there point of view this makes sense, if you think BTC will drop from here, your alt $ value will drop, too, so its a good exit point for them.
Just saying, there is maybe more than just a name change, its more a problem that the alts are all traded against BTC. (So if BTC goes down and you stay in an alt, which seems to drop, too, its just logically to get out, before you make double the loss because of the alt and btc.)
Traditionally alts have gone down against btc during beginnings of run ups and then gone up again nearer ath's as people look to diversify so it's not a bad conclusion.
