The expression "Beauty is in the eye of the beholder" surely applies here. My own opinion, for what it's worth, is that QE2 is a beautiful example of the marine architect's art, but as Bunkerbarge pointed out, when she was launched, she was regarded as being too "modern". The squared off stern of the 2 new Queens does not appeal to me, it is reminiscent of a Ro-Ro ferry.
Cos818, you are quite correct about the name of the new Queen Elizabeth, according to the Cunard web-site there will be no number attached to the name. It will be built by Fincantieri, as was QV.
As far as the sheer of the decks goes, I will let you know next year, as my wife and I are booked on the return leg of her final World Cruise, from Sydney to Southampton. We booked in January, and at the time had no idea that she would be sold, so it will be that little bit "extra special" to be leaving Sydney for the last time aboard "The most famous ship in the world".
