I could be wrong, but I think he's saying that the taglines will be the same for Anaconda and Lockhart, not necessarily the price. So, Anaconda will be announced as "The World's Most Powerful Console" while Lockhart will be announced as "The Best Value in Games and Entertainment". Though I suspect the pricing will be very similar to $500/300 based on earlier leaks.
The image was photoshopped so I dont see why he would include the price if he were not alluding to the prices being similar.
Might be from an internal Microsoft document, he laughed at someone who suggested it was photo-shopped and then said the image wasn't made by him.
