Think he will continue to do what his volume 3 is doing, affect all major events in an unpredicted way from his own series. And BTW he still has to save the universe in his Deadpool corps run which will end on Heroic age time. 
A good thing though is that deadpool now has this "hero" thing going on with him.

hes going to make disturbing yet funny jokes while doing horrible/hillarious things to people

I think what will happen is that Deadpool will try to be a hero that goes by his own rules. And I believe that he will have a run in with the avengers. Oh and he might fight lame villians

alot of pointless stuff

He becomes a hero by using a robotic suit of armor and teams up with his sidekick Weasel (Who also has a suit of armor) and the two fight super villains in Las Vegas but Deadpool is probably going to screw it all up in the end.
 
The only way to find out is if you read Daniel Way's current Deadpool arc.
