It is hard to tell at this stage because nobody has the files, although, yes I do think this game will be easily modified.

there probably will be... oh well

Rockstar says that if people go out of hand with modding.Modders will only get to play with other modders

I hope not, they are going to abuse their mods, and get a unfair advantage. :/

But as Rockstar said, they are going to put cheaters and modded into a separate group. It's okay to me.

Nope it will get patched.
I doubt it,they patched it for Gears of war 2 because it became a issue.
And will do the same hopefully for GTA 5

Well if there is you won't get to join there game. All rockstar games now have a cheaters pool. All modders, boosters, and any other ways people exploit the game are put into this pool. Meaning cheaters can only play with other cheaters basically. And if anyone finds a way around this they will most likely just be banned from GTAonline. They prob have a way to detect if someone is using modifications. So in conclusion YES there will be modders. But you won't have to worry about them because you won't be able to play with them. The same thing happened with Max Payne 3.

doubt it because there is two disk one the mandatory install and the other the game.

There will always be mods... whether or not they get online is a different story... lol and the idea that they will separate the modders from you is dumb lol 1 they can easily make new accounts + there is a reason they are called mods lol...

If they do that then they could just ban you're console from GTAonline like treyarch did with black ops mods.

EDIT:Things have changed. Developers have got smarter. Look at World At War for example, the next game treyarch made after that was black ops and you could not iso mod that even though zombies was in the default.xex. There will always be Jtag mods though. Sorry i really should take this to the rant forums.
