It's a fireside chat, so don't give your hopes up about Gemini. It's not happening (yet!). Anyhow, this conference is basically a bank-run event, as you can see from their speakers list. Also, there is a hackathon, where you can see the banks want you to build their 'blockchain' apps for them! lol
In case you didn't know what they are looking for, read how banks plan to use blockchain tech for some ideas.
