I had to quickly scan the last week of posts over the past 10 minutes to find that out myself.
The conventional wisdom from more than one insider is that a direct clone of Cars Land for DHS is off the table, but there might be a D Ticket dark ride based on the Cars movie coming to DHS. But the full 12 acre Cars Land with three shops, three dining locations, two C Ticket rides, and one massive 6 acre Mega-E Ticket at the end of the street called Radiator Springs Racers? That's apparently not gonna happen.
Now the insiders are talking about a Star Wars land coming to DHS instead. Which could be a lot of fun.
