If there are in fact more bonus features than what has been announced, then I hope that they get announced soon.
It's interesting that Bruno is illustrated on the page for this. Bruno has rarely been included in official illustrations. Also, I have read that Bruno first appeared on Sesame Street in 1978. Of course, I first read that at either The Sesame Street Character Encyclopedia or The Complete Henson Database, two places that don't neccessarily list their sources (and when I first read about when Bruno debuted, it said that he last appeared in 1990, but I knew that he appeared in Big Bird's Birthday from 1991, he appeared in the episode where Hooper's Store was rebuilt, from the 1990-1991 season, and I recall seeing part of an episode in either 1992 or 1993 that featured Bruno. Then agaoin, that could have been an insert or even a rerun from a few years back). Of course, we know that Pinball Number Count will be included, and that sketch premiered in the eigth season.
