I can't see them randomly deciding Terry is worth spending 3 characters worth of resources on. That's insane. Bare in mind all Pass characters are priced around the same, are probably budgeted around the same and thus require the same amount of resources to implement. Even Pirahna Plant who didn't come with a stage or music isn't much cheaper.
If Terry is 3 characters, expect Fighter 5 to be "Banjo & Tooie" and they're just a reskin of Banjo & Kazooie because they'll definitely have to cut their budget down afterwards.
