Both. The pbass will grow faster than the pikes, but they are both pretty fast growers. It took around six months for my pikes and pbass when I had them to out grow my 75gal. They are predators, so they have to grow faster than their prey. 
Unless you start making plans soon, chances are you'll be hard pressed to find a new tank in time. Its not a quick process to find a larger tank, get all the equipment, and set it up. Not that cheap either.
