This new TV spot doesn't contain any grand revelations - it's mostly just a cut-down version of the trailer that surfaced on April 8. (It's from the Han Solo Trilogy, which you should definitely read even though the books are no longer canon.) Ostensibly, others picked up enough to be able to understand Chewie as well throughout the trilogy.
There a number of high flying action scenes with the Falcon evading Imperial tie fighters. There's Han Solo shows the alignment of cards Chewbacca, and the furry mechanic in his usual manner emotionally and with shouts the man explains what he thinks about this game.
I mean if anything, we're finally gonna get more Lando Calrissian, and that's probably the only thing that can make up for the lack of Finn in TLJ. Chewie looks away in disgust.
Solo: A Star Wars Story is an origin story about Han Solo, starring Alden Ehrenreich in the title role. The Falcon then jets off into hyperspace. Ehrenreich stars alongside Woody Harrelson, Emilia Clarke, Donald Glover, Thandie Newton, Phoebe Waller-Bridge, Joonas Suotamo, and Paul Bettany.
A new adventure with the most beloved scoundrel in the galaxy.
That tells us that the Corellia of Solo: A Star Wars Story may be slightly different to the one uncovered by Empire, but there's still one or two shreds of information about Han's roots. The movie is directed by Ron Howard.
