David,
I did a quick search on this as I was pretty sure that when LR mated the TDV6 to the 8 speed they introduced the rotary shifter and here are a couple links showing the LR4/ Disco4 with the rotary shift knob and paddle shifters:

To be honest with you, all of the European vehicles imported to the US are always one or two years (sometimes more) behind the European version (LR, BMW, VW...)
I do not mind the rotary shifter as you get to shift the gears with the paddles if need be and in some extreme situations it might be better to have both hands on the steering wheel.
I believe the article points out that the reveal will take place in September so only a couple more months to wait... who knows maybe the body design will actually be slightly different...
