I remember comments from both companies with the mid-gen refreshes regarding waiting a year so they can price within the acceptable price-range. Also likely why the X outstrips the Pro. A year seems pretty significant. Beyond that, all these insiders are acting like they know anything beyond speculation... and as I said before- they never get it right until far closer to release.
Are you familiar with Jason Evangellho? This isn't some random Redditor pushing bogus rumors. The guy appears to have real credibility.
