No word on whether he'll wear the classic 60's suit, although that mini-fig design suggests it's just a cameo as he is now: really old. Remember kids, we're all going to die.
West will be making an appearance at the LEGO Batman 3: Beyond Gotham panel at San Diego Comic-Con at the end of July along with other members of the dev team and cast. I'd actually love to see that - it'd be really interesting to hear stories from the old TV show. (via IGN)
