Amazon.co.uk is currently listing the new HTC Desire S for pre-order for £419.99 (~$650) with a release date of April 18. Pre-release info from retailers should always be taken with a pinch of salt, as they have a habit of setting wildly-inaccurate pre-sale prices which are then changed once the official pricing is known. That said, £419 is a believable figure for the Desire S -- its predecessor sold for almost exactly this price at launch, and the Desire HD currently retails for a similar amount in the UK. It's impossible to verify the release date, although obviously it falls with the Q2 2011 launch window given by HTC.
Elsewhere, Amazon Germany lists the HTC Flyer tablet for pre-order with a price of €669 (~$900). Yep, that's a lot of money for 7-inch tablet, and it's a figure we're fully expecting to change closer to release. No release date was listed for the Flyer, but it too is slated for Q2 2011.
Amazon Germany is also listing the Incredible S for €519, the Wildfire S for €299 and the Desire S for €499. Again, these are believable prices for these phones, but there's no way of verifying them at this early stage.
