The awning may be extended further on this end, too.
The building previously sloped out into the sidewalk at this end. The decorative towers also had slightly sloping bases.
It’s possible the decorative towers are gone for good to create more space for guests to walk this way to the new coaster.
Disney has not announced an opening date for TRON Lightcycle / Run or a timeframe for the refurbishment of Tomorrowland Light & Power Co.
The decorative towers are visible in concept art for TRON Lightcycle / Run, but things can change between concept art and the final product. The art also makes Tomorrowland Light & Power Co. look more white and blue than it currently is. Maybe it will get an updated paint job before construction is complete.
