I hope GSP returns in 2015 and has 3-5 more fights left in the tank.
The WW pool has never been so deep and matches pitting him against Lombard, MacDonald, Lawler and the Hendricks rematch would be the highest selling UFC ppv's of the year. Wins over the bunch would secure his legacy even more (if thats possible) as the best WW and get more of the masses to agree he's the MMA GOAT.
GSP returns at UFC 200.
Lyoto Machida fights for 5 more years.
LSH will appear.
