However no further details posted by the developer relating to when the ROm will be released. But it's understandable, since it's in the early stage of booting development therefore there are plenty of bugs which affecting on the phone's performance, such as the touch screen is not accurately working, noticeable slowdown and some animation hiccups.
And things that work: the capacitive navigation works, and ICS is accurate enough in disabling the virtual nav buttons that are seen on the Galaxy Nexus.
Again there is no ETA on the ROM release because there are plenty of works to do before it's fully ready and improve its quality. And once it's released and available to download, I believe a lot of Android folks will get their hands on this "amazing toy" and improve what it can offers into the highest level possible.
