I picked up Tom & Jerry Tales: Vol 4 on DVD recently and was pleasantly surprised that Spike Brandt and Tony Cervone directed an entire episode that consists of 3 cartoons.
"Don't Bring Your Pet to School Day", "Cat Show Catastrophe" and "The Cat Whisperer" are very well directed. 
Since both Spike and Tony like to take a hands-on approach to their cartoon direction, they were both responsible for the storyboards, the character designs and the prop designs.
I'm glad that these two cartoonists are involved with the new show since they were directors for 2 other recent Tom & Jerry projects, "The Karate Guard" and "A Nutcracker Tale".
They have been primarly Warner Bros Animation directors going all the way back to 1996's Space Jam. They also developed the Duck Dodgers television series and directed the first Baby Looney Tunes' cartoon "Little Go Beep" featuring Baby Roadrunner and Baby Coyote. Too bad they had nothing to do with the television series....
I hear that both directors have been working on more and more episodes of Tom & Jerry Tales and I hope those make it to DVD eventually, since that's the only way I see the show.
