You could play on Live as long as you were actually invited to the preview and didn't just download the version floating around the internets. The only issue with last years preview from memory was that it had the potential to kill voice chat with non NXE users and this was rectified as soon as all users had access to NXE.corrosivefrost said:Has any mention been made as to whether there are negative effects of participating (like last year's preview making it so you couldn't play on live until the update went live)?
