According to what I read last night,1-16, the airplane will roll out. Taxi test will be later. This is an unveiling.
Also from what I read, the airplane is still a little overweight. It was as much as 8000 lbs over but now its down to 3000 lbs. Hopefully for Airbus, this thing will fly but all bets are off until the weight thing is fixed.
If two people agree on EVERYTHING, then one isn't necessary.
