Sony just announced the upgrade to its Sony A55, the Sony A57. This model uses the same sensor as the A65/A77 in a 16-megapixel size. Looks very similar to the A65. Differences are the EVF is better on the A55 but lesser pixel compared to the A65/A77. LCD is standard-tilt unlike the 3-way tilt LCD seen on the A77. No GPS and Top LCD display. All in all this will be a better option if you cannot afford the A65/A77.
