It's super hard to predict Dota 2 new meta because you get changes on pretty much anything, maps, heroes, items and even base mechanics like atributes.

My best guess is the new item who grants immunity do damage when you are near death (Aeon Disk) may be op coupled with a controller support you can't burst down anymore.

I also think the new consumable Refresher Orb may create some near insta-win situations if the player plays his cards rights, specially if you add  the normal Refresher Orb to the mix. Stuff like Sanity Eclipse x 3 or Eye of Storm x 3 or just an right-click carry with BKB x 3.

Look like a good patch, and the previous patches all been balanced and fun. Dota community is lucky to have Icefrog on the whell.
