For the first time the A7r is in Stock and shipping via Amazon US itself (Click here to grab it). Amazon says that it’s in Stock but requires 1-2 days of process! UPDATE: It is also in Stock (with free extras) at Focuscamera (Click here).
P.S.: Deal of the day on eBay is the [shoplink 23280 ebay]Sony 2 Pack of 32GB SDHC/SDXC Class 10 UHS-1 (Click here)[/shoplink]. grab them if you buy the 36MP A7r :)
