Lookin' good!
One thing I would have suggested though: List the manufacturers somewhat in order of importance. Since people are going to read the marquee starting at the top-left, they're going to read Stern well before they reach Atari and Namco. Also, do you need both SNK and Neo-Geo? Maybe swap the Neo logo with Gottleib. I'd say most of the companies in the bottom row should be bumped to the top row. Some compromises will have to be made to get them to fit correctly, and some of those choices are going to be personal. If you really dig Berzerk, then Stern may be towards the top of the list.
Not really a huge deal since you said you already sent it to be printed.
