I'm planning to get one. I have the Move controllers which are fully compatible with PS4, so I will be able to take advantage of any Move enabled game that might come out, including Move enabled PS3 games that come to PS Now.
And of course unlike DS3, the DS4 is a poor man's move controller, so with a decent install base developers will might see how they can used the light bar + camera for changing up gameplay a bit. But it'll still be a brave developer who makes a hardcore game with mandatory camera use, so most games will be camera / Move use as optional.
