Casio upped the ante with the announcement of two new cameras in its popular Exilim series of digital cameras. The Casio Exilim EX-Z6 is a 6-megapixel camera featuring a nice 2.5" preview LCD screen. The EX-Z6 offers 3x optical zoom - somewhat of a standard in entry-level cameras - and is expected to have anti-shake DSP capabilities as well.

The second Exilim is the EX-Z7, offering images at 7-megapixel resolutions. Like the Z6, it offers 3x optical zoom and a 2.5" preview LCD.

There's no clear info on when the two cameras will be unleashed into the markets, so check back later. For more, read Casio EX-Z7 and Casio EX-Z6.
