I think we're going to start seeing press conferences that start getting more pointed with what is being said. I feel like VR will likely try to instigate something with what appears to be a seemingly off-hand comment that is anything but. Psychological warfare has always been in his bag of tricks, and I'm actually more surprised that we haven't seen anything yet between him and Lorenzo. Though I wonder if he is not doing anything so as not to provide Lorenzo with additional motivation.
My guess is we'll see the first cracks in the build up to Motegi. Lorenzo is going to be the odds on favorite to win, and VR may start up there, or see if the media starts something up that he can then feed.
