Well, I'll bet ten bucks that they're bitter about the current state of the scene... the last advantage that the X-Ecuter had, ease of installation, is now superseded by the Xodus. I'll bet another ten bucks that they'll shut down again, and pop up as another group... again. They don't seem to take the bottom of the hill (compared to the top of it) all that well, if you catch my drift.
Last I heard of 'em doing anything with, well, anything, was stating that to get around the 'V2' XBox protection(s), it'd be a small hack that 'they had but are working out the bugs'. In other words, another effort from them to gain status in a community that's just about forgotten about 'em.
I wish 'em luck, but like I said, they don't take bumps in the road well (I still remember the whole "X-Ecuter is superior, all other modchips are inferior" line).
