Sony will soon announce the release of a couple of new cameras, the DSC-TX1 and DSC-WX1, which are based on its fairly new DSC-HX1, according to a SonyInsider report and listings on Provantage.com. The announcement is expected to come before month's end and the pair will build on the HX1 by replacing its 9-megapixel sensor with a 10-megapixel unit. Both will also be capable of recording 720p HD vi
