This is the kind of rumor which in most cases are wrong. A dpreview forum user posted following text:

“Today I was at Mediamarkt (an European chain of stores) and checking the prices of a the Canon 550D and 580EX flash. I asked for some advice from a sales person, and he urged me not to buy the 550D and to wait a little bit longer. According to him Sony will introduce 4 new camera’s arround april/may. The A1000, in the 2999 euro price range, aimed at the professionals, a A7xx , a A6xx, and a A4xx model.

According to him the Sony A6xx will have better specs than the Canon 550D.

Sounds exciting, let’s hope he isn’t pulling my leg”

Let’s see if I can get some more infos about that rumor. If you jnow something feel free to send me an email at sonyalpharumors@gmail.com or use the contact form on the right sidebar (you can also keep yourself anonymous)

P.S.: What I heard from our sources that there will be new cameras in MAY. the mirrorless cameras and at leat one more Alpha camera.

Xatakafoto.com (spanish) has taken a screenshot from the new Sony mirrorless teaser. Analyzing the screen you learn following about the camera:

Integrated Flash in auto
AF-S mode
Filters?: “FH Movie”
Face recognition
Object tracking (focusing)
Some kind of image stabilization (or lens IS indicator)
Easy modes (Olympus Pen LiveGuide-like): Background Defocus
Shooting tips (like Olympus E-PL1)
Easy menus (icons, feature guided)

Finally some good news!
According to our sources Sony will officially release the new mirrorless camera system in May! Honestly that’s earlier than I expected.
Three trusted sources confirmed that rumor. One of them is the same source which told us about Sony unveiling mirrorless mockups and the A7xx prototype.
In this case we are 99% certain that rumor will become true!

As soon as we have detailed final specs of the cameras we will give it to you!

P.S.: Yesterday we told you that the new firmware for the Sony A850 and the Sony A900 have been postponed until May.

Few days ago one of our trusted sources told us that Sony almost finshed the new firmware for the Sony A850 and the Sony A900 . He expected the official release for late March. The same source contacted me again and told me that the release has again be delayed. He didn’t gave me any reasons for the delay.
Also a second trusted source could confirm this rumor so I guess there is no way out form that bad news :(
