At this moment in time it's not a problem. I would imagine in three months or so, MS will release a new dash update that will bjork our jtags. Whenever the next dash comes out that requires a bootloader sequence (apart from the present 8955) there will most likely be a month or few while we wait for a wonderful group of master hackers to create a new dash version for XBR consoles. I don't think MS is too concerned with the XBR consoles that already exist, they've already blocked our ability to make new ones. That I believe is their objective. But I don't work there, and have no idea what they think.
If I did work there though, I would freely leak out every scrap of info/prog I could get my hands on relating to the 360. And spend a few years in prison while you guys enjoy the fruits of my theft.
Getting around dash updates is easy, and you can easily do this by removing the update files from your disc as you're ripping them. Now getting past system updates that would change boot-loaders
is a different matter. Simply removing the update would prevent the update from occurring, but if the game tells the box to boot through a different set of fuses that what is presently being advertised as "installed" The game would refuse to boot. And we would be stuck without new games for a few weeks while we wait on the hackers to do their magic, for a new XBR.
