If the a380 turns out to be a huge success in what most consider the short comings of the current ini lineup (in some areas) such as flight dynamics (please no helicopter takeoff and liftoff at 5 degrees) and systems. Will the a350 V2 only add new features and benefits from the a380 like say the foley system in this a380, sounds, new OIS/EFB or could it potentially entail a rebuild of the a350, such as cockpit geometry and systems as well.
Not asking for a full rebuild but there has been a couple of things inibuilds firmly believes they are correct which (such as data from flight model, despite using rw cockpit videos where for example we can see the a350 won't usually lift off at 5 degrees and be very quick with it to)
Also, cockpit geometry, the windows are to large and this has been reported many times and it's very easy to see the difference in photos, the centre glareshield panel is thicker and shorter. I understand that it will affect livery painters although they take pride in their work and would be able to push a fix out to their liveries quite quickly

Yes, I consider the issues concerning the A350's takeoff at a 5-degree inclination and the excessively large cockpit windows to be of relatively substantial importance.
