Hmmmm seems like what people forget is that the BUSA was designed for one purpose to win the SPEED WARS of the late 90's. With the signing of the PEACE AGREEMENT aka restrictrive speed limits there no need for anyone to produce a bike faster than the busa. In all honesty there's no profit in producing one --just ask KAWI about 12 sells. The busa is still selling almost every bike they manufacture, demand is steady, and the R&D is already paid for ... so why invest in a new design when you already have a bike that has achieved Cult status. Anything they produce or any major mod they make will end up being less than expected and the bike will be compared to that first linage of busas, which were, are, and most likely will reign as king of speed.
My money says prepare for new graphics.
Oh as for lighter weight, would be great, but would make the bike faster and perhaps cause suzuki to restrict the power train or top end in such a way that the "magical" TRE can't override. Anyone got a 99 or 00 in stock condition for sell --- its gonna be a classic!
