I'm pretty sure that the animation on the ACO website shows the apex of the revised corner brought nearer to the esses, and made quite considerably tighter: so more like a tight 110 degree bend, rather than the broad, fairly open sweep that was Tertre Rouge. So slower, but with a wider gravel trap: much safer, but losing something, as usual.
