Analyst projections are based on their proprietary demand models (a set of statistical/regression formuli key'ed off 100s variables like product attributes, competing forces, content contributions, ... plus any other VooDoo variables).
You forgot a huge issue with pre product analysis- focus groups. You can not underestimate how much weight they have on analysts predictions- and unfortunately they are almost always too small to get anything remotely resembling a good sampling.
For the launch price issue-
Microsoft's Xbox 360 is going for the gold on eBay. According to eBay president and CEO, Meg Whitman, 40,000 Xbox 360 consoles have sold through the online auction site. That's 10% of the total number of units estimated to have sold in the U.S. since the product was released.

Another-
The small supply and large demand moved many to "flip" their Xbox 360 purchases on eBay. During the week of Nov. 22 through Nov. 28, each successful Xbox listing on eBay garnered an average of 19 bids, and sold at an average price of $718.

Using basic market principles the fact that people were not willing to sell their 360s at that price point(given that the demand was clearly there to support such transactions) obviously MS could have charged a lot more for their system.
As far as pricing moving forward- why does anyone think that the 360 will have a long term price advantage? Right now the big difference in price can be narrowed down to one device- the BluRay drive. It is currently an emerging technology, in four years it will be a commodity. Xenos+Xenon are more complex then Cell+RSX, RAM is comparable between both systems as is almost every other function of the machines. Looking out long term it seems to me that Sony should be able to, worst case, pull nigh even with MS in terms of cost per unit produced. What is the difference in production cost between a CD drive and a DVD drive? $1? less? You can pick up high speed dual layer DVD burners for well under $40 now, devices that were four figures not all that long ago. BluRay is not a long term major factor for the PS3, it is a short term issue- history has shown us this time and time again. MS's ability to move to a single chip GPU solution seems like a larger hurdle as far as pricing is concerned to me. Then you need take into account that MS has to pay another company to handle the fabrication and production of their machines, something that requires them covering another company's margins(even if they are operating under none for the 360 hardware themselves).
What exactly leads people to believe that Sony will be at a long term pricing disadvantage? The only possible reason I can see this as being a viable concern is if MS ends up subsidizing the 360 heavily this generation(which they seem to be stopping).
Sony also does have the advantage that they will be a BluRay player. Right now people are laying down $1K for players that do nothing else- I think there will probably be a market for $500 units that also serve as a next gen console in four months
