GBP 484.79, to ship in 2 to 3 weeks
the HTC One X with Tegra 3 and HTC One S with Snapdragon S4 chip should be ready to ship in two to three weeks.
This might be an optimistic shipping date, but at least you can order these phones today. Handyshop.de store dares to tell you that HTC One X with quad core + one Tegra 3 will be available in two to three weeks while PDA Max is a bit more conservative telling it can take good 4 to 6 weeks before you actually get your phone.
The phone should end up with 1.5GHz clocked quad core processor, Android 4.0 with Sense 4.0, 32GB storage and 1GB RAM but no mini SD slot for further memory upgrades which will disappoint many. The phone has a 4.7-inch display that should be enough for nice surfing.
We know that the HTC One X is listed for even less money, but €599 is the more realistic price from stores that kept good shipping records in the past. The HTC One S is 4.3-inch phone with 16GB memory and Snapdragon MSM8260A dual core at 1.5GHz and this one sells for an average of €499.
