An eagle-eyed user has noticed that the Sony a500 and a550 references were in a listbox that is part of a camera registration process. There are actually four references: DSLRA500, DSLRA500S, DSLRA550, DSLRA550S.
At the moment, there’s not much more information but it is believed that the upcoming alpha 500 Series will have video-recording capabilities, unlike the recent Sony alpha models. This was spotted on sonystyle.ca. [via photorumors]
