If you really want to have a sneak peak there is a few items show in the screenshot section if I'm not mistaken but you won't see more than 10 items I think.
For example, the new homing nova shot modifier is shown :
viewtopic.php?f=36&t=149&start=1260The text associated with it in the patchnote is quite funny too.
Or a new naginata that synergize with broadside (which now work with naginatas too) and fire/lightning :
viewtopic.php?f=36&t=149&start=1250
