haven't you asked the basically same question already?
there will be large creatures, there will be small creatures, there will be medium creatures. as in every AP.
there will be points in the AP where you have the chance to grapple your opponents. there will be points in the AP where such tactics might not work that well.
also, if I were your GM and would find out that your begging the internet for spoilers of the campaign I want to run with you, I'd make sure your not in my campaign any longer.
