in my way of seeing the SHs after 2 years they would be more stronger than before and more prepared for battle.


 * Luffy : having control over his haki abilities to fight against those logia users equally, and learning more attacks that will surely kick ass (maybe more gears too).
 * Zoro : would improve his swordsmanship as he is with Mihawk, and after that it would be great if Zoro would learn more moves that will surprise Mihawk next time they meet and clash.
 * Sanji : will learn how to use the "attack cuisine" technique to make food to increase body strength for the whole crew, and it would be awesome if he would learn to use okama kenpo in a "cool not-really okama type of way".
 * Usopp : will improve his marksmanship skills, and finding some new plants (or maybe some other things that lies hidden in the island) that can be used as his new weapon/attack.
 * Nami : will absolutely add more climatic attack on her clima-tact weapon as she combines it with wind knots and weather balls, and she would learn the weather changes and patterns in the New World since she's the navigator.
 * Franky : will definitely come up with more new weapons and maybe he can find something useful on Vegapunk's old lab that would increase his knowledge more about modern technology, and maybe he will get some information/idea on what is the weakness of Vegapunk's creations.
 * Brook : don't about what he can get from the island he's in, but maybe he would learn something from the Long-arm tribe as we can see their abilities can chop and trigger explotions on the victim as Apoo did on Kizaru in Sabaody arc, maybe he will eventually befriends with them.
 * Chopper : he surely will get enough knowledge on medical treatment, giving him the posibility to cure any kind of disease that even Roger suffered from as they went on the Grand Line. also, he can master all of his forms, especially his monstrous form, without the limitation on using the rumble balls.
 * Robin : would become more knowledgable as she will be with the Revolutionaries. maybe after 2 years she would have weapons up on her sleeves (imagine Robin wielding 5 pairs of different guns at once).

~i doubt that all of them would learn Haki, since not all of them is with a Haki user/master.
