German / Austrian Amazon will have the slim version of Playstation Portable for sale in nine to twelve days. Even the price sounds about right, as it will cost about 170€ when available.
The store is taking pre-orders for two versions: the black one comes first, and at a later date Sony will come out with a white one. The black one will be known as PlayStation Portable - PSP Konsole Slim&Lite Piano Black (Base Pack), while the white one will be known as PlayStation Portable - PSP Konsole Slim&Lite Ice Silver (Base Pack).
You can pre-order one here and it comes with free shipping, at least from this Amazon.
