Fair enough, I just find the only bad thing with the A series were the batteries and this newer version which apparently doubles the pervious gen was quite appealing. But as you're getting this on a discount you can just get a few more batteries on the side and save yourself a few quid over the A9.
Did you get the A7Rii? If you're not in a hurry then maybe wait for the A9 when it comes out in June.
