Last night, Major Nelson announced
that one final wave of invites to the NXE preview program were being sent. Specifically, another 10,000 lucky gamers have been given preview access. If you signed up for the initial phase of the program and have yet to be invited, make sure to check your inbox, as Microsoft sent out the final invitations last night (don't forget to check your spam). Remember, this is the last wave of invites, so if you haven't made it now, you're not going to. But hey, don't sweat it if you still haven't been invited, as the official rollout is only five days away anyway.
[Thanks to everyone that sent this in]
