Wherever the show is taped, as long as it continues to be produced in a way that makes it enjoyable, does it really matter? Studio 33 aka Bob Barker Studio might be historic, but things come and go. If they really wanted to mimic the old studio, I'm sure they'd find a way if they felt it necessary. If they even went so far as to rename the new studio Bob Barker Studio or the Bob Barker Stage or something else, I don't see a problem with that though I suspect it's unlikely. I could feasibly see the intro being changed to reflect the new location or revert to using the "television's most exciting hour of fantastic prizes" line. In any case, while it's somewhat sad to see the show have to move, it's not going to ruin it.
