Here's a slightly more recent post as well.

In that post you can see Dean and Roswell's new look and early sketches of the others. (Though each of them have progressed a lot since then, pretty sure Tyson is finished and the others as well by this point). All the guys will have eye color, various poses and expressions. The new title screens and recent cgs show off their final designs pretty well also.
And honestly, I think it'll just be an adjustment since we're used to the way the characters look after all this time. But I like the newer ones more at this point. Tyson for example isn't as wide as Dean or so fluffy now which fits how he's described in game better. Thin, unapproachable, and scruffy.
