Sony Cybershot TX55 is now officially announced
The camera has a 16mp backlit Exmor-R CMOS sensor, 5x folded-optics lens with Optical Steady Shot, starting at 25mm equivalent, 3.3" OLED display (1.23 kilodots). The whole camera is actually slimmer than a AA battery says the product description.
Because of the slimming down, Sony has ejected the SDHC memory card for the smaller microSD/microSDHC and the equivalent smaller Memory Stick. Slowly but steadily the number of microSD P&S compacts is increasing. It will be interesting to see whether this happen only when camera-size dictates it, or whether manufacturers will be tempted (perhaps by the smartphone link) to offer microSDHC in more models.
The new camera is already available for pre-order at Amazon for $350 in your choice of four body colors.
