the valient and valient (sp?) window is still there, i was shown it on my tour when i started the college program a few years ago, and it was still there this summer (for those who don't know about it, go over by echo lake, and look above the peavys pipeline, cola slushy stand)
as for merchandise, if any of you are pin collectors disney has put out dozens of roger rabbit pins (including ones of jessica rabbit, baby herman, benny, roger, even some of the weasles and the club bouncer pins have showed up though they may not be official releases by disney)
-and for you non pin traders: the roger rabbit patty cake club (?) shirt has been spoted several times i believe at the world of disney store at downtown disney, its a black bowler style shirt, very nice. (my friend has it)
they had a few pictures of roger up in the cast member areas at disney-mgm with other pictures of retired characters like the ninja turtles (not sure if they still do)
my recording of spectromagic has roger rabbit in the part where the genie is now, he definately got replaced by the genie.
