Sony Japan posts Alpha A99 detailed Developers Q&A (computer-translated)
Sony Japan has published a detailed six-page Q&A article with the Sony Alpha A99 developers. You can read it in Japanese if you can read Japanese. If not, the best bet is to paste the url in a Chrome browser window, and let Chrome do the translation (look for a prompt by Chrome for computer-translation right below the url-address bar/box). The manually-generated computer-translated links seem to have formatting issues, but maybe they work on your system: may have formatting issues.
Based on the computer-translation, they talk about a lot of things, including the links in the naming scheme (A900, A99), the choice to "remain" at 24-full-frame-megapixels, autofocusing, pellicle mirrors, the XGA OLED Tru-Finder, ergonomics, and lots more.
