I have heard, from the boeing website that they are working on a 747-400X. Waht exactly is the 747-400X, and will it be a competator for the A3XX?

The 747X program is designed, apparently, to compete with the A3XX. The 747X models are, 747-400X, 747-X, and 747-400X Stretch. In service they will probably be the 747-400ER, 747-500, and 747-600.
The 747-500 has more range than an A3XX, but neither the -500 or -600 get close in terms of capacity OR comfort. The 747-400X itself is just a 747-400 with updated technology and vastly improved fuel efficiency over the 11 year old jumbo. It would also feauture a 777's interior styling. As said, however, the 747Xs aren't quite as big as the A3XX, so they will appeal to a slightly smaller market - this is good for United Airlines and other US airlines which are wary of ordering the mammoth A3XX which seems mostly useful in Asian areas.

B 747-400X is something similar to the current B 747-400 with approximately the same range as well as capacity. However, it would be more user friendly, presentable as well as environmental friendly than the 747-400. At least, it saves oil.

Hope this helps! : )

Thanks for the reply's guys, and especially the info. Waht do you mean by more comfortable?
The A3XX is ofcourse much larger, but exactly how much larger, and in what way more comfortable?

I believe, from the pictures that hte 747X will be very nice too, but in a way a copy of the 777. It has the similar windows, stowage bins, etc.

When will the project be started? Or has it already? When will the prototype be finished?

Boeing started the 747X program nearly five years ago, but shelved it in 1998 as it had no market. The 747X is now being offered to airlines, but none have ordered. Boeing will not launch the plane officially and begin designs, tests, and prototype construction until orders are made. Orders are expected in the next few months and hopefully many of them! If Boeing gets the orders they'll proceed with the jet, we should see a prototype either in late 2003 or more likely in 2004. The aircraft would enter airline service either in 2005 or 2006. Normally it would have to enter service after the A3XX as it isn't being launched until after it, but Boeing has already done considerable work with the plane AND it is not an entirely new jet which helps out a bit in expediting the design process.

As far as size is concerned, the 747XStretch will hold about 515 people, while the A3XX-100 will hold 550 and the -200 (the 'stretch version') up to 650. Here is a comparison for the three 747Xs and the three A3XXs being offered in terms of capacity:

747-400X vs. A3XX-50: 416 vs. 475
747X vs. A3XX-100: 430 vs. 550
747XStretch vs. A3XX-200: 520 vs.650

As far as comfort is concerned, the A3XX's fuselage is 3 feet wider than the 747's, but the seeting is the same (2-2-2 first, 2-3-2/2-4-2 business, 3-4-3 econ.) so there is much more space per seat and aisle. The A3XX's upper deck is also TWICE as wide as the 747's, having room for many many more seats and two aisles.

As you can see, the 747X is substantially smaller in terms of capacity.
