Maybe he will have to train(something he really doesn't do, since his powers are natural, not like batman and others.)
Maybe he trains and pushes his powers even further by doing this.
He becomes several times stronger,faster,more agile,quicker reflexes,and becomes more durable.
Hell maybe he finally makes use of that genius I.Q. and creates a potion that boosts all his abilities(he should be able to.)
They can't change Spider-Man's powers!
spider-Man has had the same powers since the 60's unchangingly (unless you count organic webbing) and they've already changed them slightly recently (organic webbing) and if they do anything rash and/or permanent it's gonna leak into the movies/ultimate universe and mess everything up. If Spider-Man "evolves" they should either be talking about an emotional journey or something he has to reverse i.e. him turning into a giant spider.
And Lord Magnus is already more highly evolved than anyone else on this forum. fools.
