So is anyone else wondering why the Hologram/Android races keep getting delayed?

Personally I'm so excited to play as a hologram that I bought like 4 extra costume slots. (Finally a good reason to have a completely different looking avatar for each day of the week)

Is it just balance reasons they're delayed? Worries about how you heal a machine? What do you think?

As for further speculation, do you think Holograms will be limited to human features, or have more of the alien gen opened up to them? What about some of the race specific things, like the Trill spots in places besides the head? Technically they could look like anyone, the only question is how Cryptic is going to limit it.

I dunno, I'm just interested in what other people are thinking at this point.
