Point taken, maybe the A350/360/370 designations missed out refer to A300/A310 follow ons, but let's face it, a shrunk 330 is a bit more likely if the beancounters have their way. It will be very difficult to squeeze any development finance out of European govts as per the 380 given the current economic climate, whereas Boeing probably will begin touting 767SE for military applications as usual.
The 60m wingspan is a bit difficult, no question, but I reckon a 767SE will have a more 777 like wing and therefore probably be in a similar fix. Thus airports will have to eventually make up their mind as to whether they want widebodies at all post 2010 or so and if so spend the money to widen the facilities.
Of course, all this is predicated on whether 330 can indeed be shrunk, or if it were just too short for the wing.
