What are you seeing in early testing for the new Core 2.0 meta?
I've been trying to test with Corp more than Runner so far, so can't say what people are doing with Corp too much. Playing Corp on Jinteki.net here is some of what I'm seeing so far.
Anarch -- Using Bad Publicity (Val and/or Mining Accident) to make runs and trashing more efficient, usually with heavy emphasis on the conspiracy breakers. Also running into Reina with Xanadu and Rubicon Switch trying to choke Corp resources.
Criminal -- No clear pattern and only a couple of games. Seem to be exploring the derez cards as a means of controlling the econ war. Inside Job has made a big comeback. Fisk Investment Seminar (and Fisk himself) is showing up a bit in an attempt to capitalize on the no-Jackson meta. Gang Sign and HQI are big piece of this approach. I've heard people say Geist is well positioned, but I have not run into him myself yet.
Shaper -- Mostly seeing Chaos Theory and Smoke, with the Smoke being pretty similar to pre-rotation builds. Nothing super consistent in the CT games I've played. Indexing is a popular Core 2.0 card.
A couple of general observations as a Corp player (mostly playing various forms of glacier):
1) I often do not ice HQ early and sometimes at all. With no Siphon or Vamp to fear, if I keep my hand clear of agendas by aggressive remote play, I often don't feel I need to spend clicks or resources protecting HQ, at least not in the early game.
2) Runners are still super rich and it is really hard to open scoring windows. Ash is a welcome include in Core 2.0, but rich Runners (and I'm hitting a lot with link) make him not so helpful.
3) Lack of parasite really make ice like Komainu and Kakugo more impactful. I'm sure there is a Jinteki deck out there that is going to be a beast to deal with. My glacier PE deck is way too vulnerable to Film Critic to be that deck, but even there it is great to play Anarch and know you get more than one turn of usefulness out of your ice before it is going to die to parasite.
These are a few early impressions I have. I'm not a very good player, so I'm sure other people have more refined analysis and a better read on what will be good or weak. Please share your thoughts and reactions.
