So what are these secret parts? Can anything about them be revealed? Secretly on the forum...

You have an interesting job.
Well I have made only a few new parts for 2013 sets, like Space wings, Chima eagle head etc.
This is because I've been busy with parts that needed a bit more development, and will be out in 2014.

So, it's almost like this one:
I see potential...
(please consider this version as well. I think it has more potential than the version you are describing)
Erik, I see you attached a 1x1 to a 1x2, instead of the 2x2 attached to a 2x2 as I had in mind.
Both pieces could enable "smart" builds, but the problem is of course that you can't put the part down on a plate, or put a plate on top of it. I already described my suggestion to Design Lab, and they are surely not fond of parts like these, which I kind of knew before hand. But I haven't given up yet.
But in recent years LEGO has focused on making parts that fit well into the SYSTEM in a natural way, so there is hardly any room for "strange" parts.
