The big questions are what will the new xbox be like ?, will it match up to the ps4 hardware ?, will they announce any new exclusive games and will they actually show the console unlike Sony did?. Who knows we will have to wait and see but to be honest i don't think it will beat the ps4, i have read reports that say the xboxs hardware is already behind the ps4 and they haven't even began production yet which isn't very promising and with the way the xbox 360 launch went with the red rings they will have to take there time to avoid anything like that again which will mean that ps4 will probably have the jump on them.
So it seems the next gen console is beginning to heat up.
