Well, the spanish site, www.tecnofotografia.com has a posting which has claimed that the Sony A1R is a fake and that Sony has the A730 ready to rock and roll!. The translated (using google translate) of the page;
A source coming from Sony itself has sent me the letter of specifications of what would be the replacement for the Sony A700, Sony A730. He told me that the leaking of the A1R is false, possibly out of this letter. Just to illustrate, say, the current out of these specifications A550 or A730 that would already be in production, but for some reason decided to get first A550. As we can see, the new A730 would come armed with almost the same specifications as the A550, as in the case of D90 vs D5000, the A730 would have the same 14.2MP Exmor CMOS sensor of the A550 APS-C format with 14.6MP effective, aluminum and magnesium, uses MemoryStickand Compact Flash cards, pentaprism with 100% coverage and 0.95xmagnification, Dual BIONZ processor, LCD 3 "swivel with 921.000pxresolution. USB 2.0, WiFi , HDMI, 7fps, 9 focus points, it would be the second sensor for LiveView, instead have the LiveView Check Manual Focus 100% coverage, in addition to the Intelligent Preview, ISO 100 to 12800, 1 / 8000 shutter speed, compatibility with the new HVL-F64AM and current, among other features, Unfortunately there is nothing to nothing about video recording. You can click on the image to enlarge and view all the specifications.
Update: I'm told my 64AM flash specifications or at least something about this new model is coming soon.
Whatever it is, either way, the flash seems like a real stuff. Anyway, the image from www.tecnofotografia.com.
And an image of the top of the rumoured A730.
