Doctor Octopus is one of the biggest villains Spider-man and is way up there alongside Norman Osbourne. If he is the main villain I for one will love it. Better him than Venom or Carnage, one mediocre villain and one awful villain....no thanks.
Thats the issue though, for a game like this you basically have to have Goblin or Ock.
We know Norman is in but doesn't seem to be Goblin currently.
Its such a base level requirement that the fact that he was hidden seems ridiculous personally.
Especially when you basically have the Sinister 6 already revealed and set up completely in the E3 trailer,
Personally Venom/symbiote, or something like Harry Goblin are worthy of the huge secrecy
My worry from that though is if its worthy of that much secrecy the story will essentially be "OH MY GOD IT WAS DOC OCK ALL ALONG!!!!"
with literally everyone saying "we know"
Honestly it feels a bit like The Arkham Knight but at least Ock wasn't presented as a new hype character.
