You have to admire CCP's daring if nothing else. A moderately successful space combat game and they are going to open up the completely unfamiliar interior of space stations with new technology, environments, and no actual game play? Very daring indeed.
They have a hard spot here. On one hand, they can't develop it into a full free standing game or feature because they are only building the basic architecture for the first iteration. On the other hand, you just know they are going to be pilloried for releasing a feature with limited game play and/or no relation to the current game. Their protestations that they are going to keep coming back to it fall on ears and hearts hardened by numerous areas of the game seemingly left in disrepair for years with no sign of revisiting.
They are walking on a razor edge with disaster (or at least bad press) on either side. Fail to release because they want to add more content and its a failure all round, but release and have the community pan it and they have to work extra hard to get good press.
I do not envy them their current position.
On the upside, the avatars in the new character creator are gorgeous so as long as Incarna has a bare minimum of functionality, such as a bar and some mini-games, it could hold water. But its a razor's edge, and a long climb back up if they fall into either side.
