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 12 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 Sony 2 Pack of 32GB SDHC/SDXC Class 10 UHS-1 (Click here). grab them if you buy the 36MP A7r
