not yet...Point is, the explosion at Osborn's lab had direct psychological and physical effects on both Norman and Octavius. It also gave them superhuman powers, undoubtedly a side effect of their exposure to the OZ. Norman, who had injected himself with OZ directly already, became this super-strong, hulking Goblin who could throw fireballs from his hands and leap miles into the air. Doc Ock, who didn't have a direct exposure to the OZ, yet was obviously still in some way exposed and affected by it, maybe inadvertently through the explosion, then came out of the explosion in a coma for three months and awakens to find out he has a mental connection to his metal arms...another obvious superpower. Maybe Harry was affected by the blast in some way as well, but his powers have remained dormant. Or...maybe they have already surfaced, and we, as readers, just haven't been privy to the Hobgoblin's/Harry'y backstory yet. After all, Harry's been living God-knows-where for the past ("only?") 9 months, with a few visits back to Pete's life, most notably in the Legacy arc, and Ultimate Six. And those words he spoke to Peter at the end of the fight in Ultimate Six would surely make sense if Harry was indeed the Hobgoblin. Perhaps SHIELD has been housing Harry all this time, aware of a "genetic modification" in him as a result of the explosion at his father's lab, keeping an eye on him and his powers while they keep his father in cryo-stasis. Now Harry's returned to New York and Bendis is building up more motivations for his hatred of Peter/Spider-Man with this new MJ as Harry's secret girlfriend before she started dating Peter twist we got in #72. Thats my theory on the upcoming arc.
