A Few Multiplayer Questions

Will the new game only allow one name per cd key. I dont like how in Rome multiplayer you can change your name anytime you want. People can spam and stuff from different names and you never know who anybody is. I like the Age of Empires 3 multiplayer set up with only one name per CD Key. Also will the new game keep stats. Such as wins and losses. Again on Age of Empire III, it keeps win-loss and xp. This would be good so you could know how good someone really is. Otherwise i am pumped and cant wait for the new game to come out.
