Just tested it, well I particularly liked the magnum pistol and then charger, can't wait to test it on versus when the full one comes, charger will be very useful to catch up a seperated person and quickly incapacite him/her, and Smoker does better damage now, which is better, for the Jokey, it looks like something easy to deal with but I think it will be useful to seperate a survivor even more if he/she didn't catch up with others, and quickly suiciding one member to their death from cliff or top of a building

Yeah the infected roles have really changed. From what I've read, heard and seen, the roles are now as follows:
Hunter: killing separated survivors
Smoker: killing survivors from cover
Boomer: blinding and slowing survivors
Jockey: damaging and separating survivors
Charger: damaging clustered survivors (or killing separated ones)
Spitter: area denial through damage
Tank: maximally killing everything
I myself find it pretty good they were able to come up with some new roles. I couldn't have thought them up myself, probably. That and the community suggested every single one, probably
