This new FW will of course be made mostly for new consoles being modded, because even if you're not banned from LIVE yet there's no way to know if MS already has info/logs on your console ID regarding timings or other stuff so even changing to this new firmware in the near future may not stop that console ID from being banned in the next wave of MS bans.
If your console is not banned yet, it's highly suggested you don't boot any burned discs, originals should be ok, even when offline (MS might be storing results of some checks in flash), until the release of the new FW.
If your console is already banned this will of course not help you ... just enjoy the offline playing on that console for now (with some games you could try using 3rd party networks like XLink Kai(info)) and maybe some day a new exploit will allow you to do more with that console.
