Input/Output of Calculator

[matalog]

Is there ant hope of having a simple or more complex input/output method of information to/from the HP Prime?

We all know that the TI-84 and its siblings had astounding success with stereo jack in/out port, which is a very simple thing.

Can we expect that we might be able to connect a particulat USB device in the future and have a similar connection ability?

Am I the first person to think of this? Should I get a proceed from all future work of this nature? Only joking.

Can we imagine a port of some sort that the non-USB-expert can program and be able to communicate with the calculator?

Is it feasibly going to happen?
