New Companion for Doctor Who!

We still have to wait until fall of this year for an new season of Doctor Who but we now know who (pun in intended) will be the Doctor's new companion! Whovians will soon be watching this young beauty Jenna-Louise Coleman alongside Matt Smith on TARDIS adventures. What do you think about having ANOTHER companion? They seem to go through them quite fast these days. Will you miss Amy and Rory? Do you think she will be a good one right here at the Doctor Who 50th anniversary? Who do you want to see come back for the anniversary? etc.
