WD declines to comment on rumours or speculation about forthcoming products.
Is it just me that sees that as tacit admission that the info is correct. If it is why not be honest and come out and say it. If it isn't, ditto. Any mistruths will come out in the wash anyway when the map is met (closely) or not.
What does a company gain from not commenting, I am sure their rivals will now be working toward this roadmap (as close as they can at least) anyway.
