I was just going to make this thread,
pros:
1. better actor to play Peter Parker/Spider-Man. An actor more suited for the part. As good an actor as Tobey is, I never felt like he was right for Spider-man or Peter. He always seemed too stiff to me. Although with each movie it seemed he was getting better. But this time maybe they can cast someone with natural Peter Parker/Spider-Man charisma.
2. Better actress for MJ, I didn't have a problem with her being MJ really, her role started making her unlikeable but that wasn't really Dunst's fault. But maybe now they can get an actress who looks more like, and acts more like MJ.
3. Maybe make things closer to the Comic from the start, like maybe having Peter and Gwen date before he ends up with MJ. Maybe make Captain Stacey a bigger part. Maybe make Doc Ock a meany, or make Goblin's costume closer to the comic. The movies were pretty close, you know until the 3rd movie. But maybe make things even closer to the comic.
4. Maybe they can tie this Spider-Man into the Iron Man movies and the SHIELD movies, making part of the Marvel movie universe now.
There might be more Pros but thats all I can think of right now.
Cons:
1. We all got to know and love the Raimi/Tobey Spider-Man movies. It just is such a shock and feels almost like the studio is saying that those movies were bad, and sort of like saying you the audiance shouldn't have liked them. Or that none of those movies mattered.
2. With Sony now having more power over the Spider-man movies, since Raimi left they will probably get a director and crew who will let them get away with more, the movie could suffer from things like forcing in Venom, turning the Black Cat into the Vulturess, using Morbius instead of a more classic bad guy, not using a classic bad guy becuase he will not make as much money for them, introducing the baby, and other ideas that might end up hurting the movie.
With the studio now in more power, that might not be so good for the movie.
3. Retelling the origin when they already did such a great job in Spider-Man 1 with tobey. Peter gets bitten, learns about his powers, becomes a wrestler, makes costume, becomes Spider-man. everything seemed so great, how can they make it new and different and interesting? Will they make changes just to make it different?
What about the costume? Will they make changes? I always thought that Tobey's spidey costume was great. We will get a bad Spidey costume just to make it different?
4. Not using certain villains, Raimi pushed for Vulture and Sandman in 3 and was forced into using Venom in 3 in place of Vulture. Then he pushed for Vulture in 4, and ended up leaving. It sounds like the studio really didn't want to use the Vulture. So its probably safe to say they will never use him. but what about other bad guys? What about Kraven? Chameleon? the Lizard? Mysterio or the Scorpion? Will the studio never use certain bad guys? And what about already used bad guys like Green Goblin (who they used in 1, sort of in 2, and ruined in 3), or Doc Ock, or the Sandman? Because they were already used does that mean they will never use them in the reboot?
There might be more cons, but thats all for now.
All in all, even though this was a total shock and punch to the gut, I think a reboot wouldn't be so bad. Maybe more good can come out of it than bad. Maybe we can get a much better Spider-Man universe out of it. It could be really fun.
