Rumored to cost about $150. Yes it costs much more than the Pi but you get what you pay for; a boat load of processing power and memory.
If you don't treat it as a computer like most people who don't use them then you already get way more than you pay for.
The vast majority of the projects the RPi are being used for could be done by a microcontroller. So when you compare them against other devices used in the same application then for the same cost of an Arduino you get 15x the speed, 100x the RAM, and Ethernet, and OS with a complete TCP/IP stack ready to go.
Anyone who really complains about the price of the RPi is expecting it to be something it's not. There are plenty of boards far more powerful than the RPi for under $100 and they don't sell anywhere near as well, don't have anywhere near the same number of projects being developed for them and don't have even a fraction of the community support.
