I think since Kubica is done with Williams we need to take the conversation about his future elsewhere.
For now it doesn't look like Robert will be racing F1 car next year, but here's something from Daniel Obajtek - Orlen CEO:
Puls Biznesu: We're unsure about Kubica's future in F1. Is his absence in this series equals Orlen leaving F1?
Daniel Obajtek: You don't go to F1 only for one year. We all know that. This is the brand recognition we were talking before. We are talking with several partners about this. Orlen will be present in Formula 1 and Orlen will be working with Robert Kubica. This is what I can say about that matter.
PB: But won't it work without Kubica? Is this a necessity?
DO: There is one condition - Robert Kubica. That's because we have research, we know his recognition in Poland and I can say this (RK in F1) worked very well for us (...).
PB: But if he doesn't race in F1...
DO: But did I say he won't be racing? I said it precisely...
PB: If he doesn't race you won't be there?
DO: We are talking (with partners). Orlen will be in F1 and will be with Kubica. I answered that!
PB: It is possible that no team will...
DO: For now we are talking. These talks are creative, intense and specific.
PB: What's your plan B if Robert won't find a racing seat?
DO: You see, you're still asking the same thing. We as Orlen have a plan together with Robert for many possibilities but there's one option: Formula One.
PB: Robert Kubica as a simulator driver. Does this satisfies Orlen?
DO: <laughs> I just answered that.
PB: He would be in F1, just not racing...
DO: We have talks, we are prepared for many possibilities...
PB: Would it be an acceptable scenario?
DO: We will give you full info soon. I will only say this: you will be pleased.
PB: When will be that?
DO: Soon. I think 4 to 6 weeks from now it will be very clear.
