We only have limited information, but details of the Sony Vaio for summer 2007 have been leaked and this is what we can tell you.

It looks like Sony is going for a pretty hefty update for its laptops, the 15.4-inch Vaio FZ19 will use Intel's Santa Rosa chipset and integrated X3100 graphics card. There's also the TZ, a reworking of the current TX series, which will be an ultra-portable figure with 11.1-inch screen, finally the SZ5 is a refresh of the SZ4.

The CZ series is expected in July, coming in a 13.3-inch screen, and the CR range, a 14-inch widescreen notebook.

TZ is expected to come with integrated DVD-DL, 2GB of RAM, 100GB HD with WLAN A/B/G, integrated webcam and a fingerprint scanner (which is either for persoanl security, or this leaked model is for the MI5).

Obviously, no prices or dates of availability yet.
