Other online retailers continue to announce pre-order availability, the latest of which is UK based MobileFun.co.uk who quote a price of £419.95. The £420 price point seems to be fairly common across UK online retailers.
The pricing of Nokia products by independent retailers is fairly competitive, often undercutting the price in Nokia's own online stores. However the N8 is likely to be in high demand for the first few months, so the usual pattern may not apply. Moreover, as with other popular handsets, there may be an initial period where some retailers charge a premium price.
However we would expect the price to start to fall three to four months after initial retail availability, with the lowest price being reach nine to fifteen months later. A good example of this is the N97 mini, which was initially price at around £450, but then dropped to around £390 and is now available for £300.
