Just found this thought it might be of interest.
This is great but question still remain!
When Apple TV 3 Jailbreaking Seas0nPass coming out so I could use my ATV Black Flash on Apple TV 3.
There hasn’t been any progress from anyone within the jailbreaking community regarding the Apple TV 3.
Fake hack going around:
I found some links with a video that there is a hack for ATV3, but I am pretty sure it is fake:
When you click on the download links, it asks you to fill out surveys etc.
I found the original link in the comments section on this page:
Posted by a poster named “H233362”:
I just found a jailbreak for the new apple tv 3.
21 hours ago.

Here is the link for the video:

If this is fake then minus karma points!
If there was a genuine ATV3 jailbreak available then you can be certain that it would be announced via the FireCore home page.
Can’t be too far off now, I’m almost done converting all my movies to m4v, I’m sure just as I finish a hack will be found 
That is wishful thinking.
When I look at all the jailbreaking of ATV3 on the web, i get just as frustrated as alot of the members in here. Im not pinning the failure on firecore, because as a developer, I know the frustration when the code or hack does not work.
But I really wish, like alot in here, that “firecore twitter” would come with more news, than NONE.
people are expecting to hear something even if its not a success history. 
Firecore are not the ones that find the exploits. The iPhone Dev team are. People like musclenerd, i0nic, p0d2g etc. Firecore simply packages the jailbreak into easy to use software. So how could they report anything if they aren’t the ones that are looking.
Ahh sorry matty, i was on the impression that firecore did the jailbreaking ;), but that explains why we hear nothing.
Be patient and keep checking Home Page before visiting forum postings…or making post when ATV 3 JB available and how long etc etc…
another , next scam http://www.prweb.com/releases/2012/4/prweb9405411.htm .
Just out of interest does any one know if they are working on a jailbreak for the AV3?
Firecore says:
What about the ATV3 and the untethered version for ATV2? Work is still underway on both fronts, and we’ve had some encouraging reports come in over the past few days. However, it’s still too early to give any kind of ETA but we hope to have more news soon. For the latest updates be sure to follow us on Twitter.
News: we have all exploits required to do a new jailbreak. I'm working on bypassing ASLR at bootup.
So cant wait
Allot of feathers getting ruffled in the JB communitiy about it going public
so it is not looking good for ATV3 JB… 
Yup,
Prices for the Apple TV 2 is going up and up and up and its very rare to find these days…
Thses prices will continue to rise…till JB of atv 3 is released…dont know when
