I actually think a fork would be an absolute marketing nightmare and Sun would avoid that at all costs.  I'm overwhelmingly bullish on this acquisition if the "token swap" he's talking about is two-way and never closes.  

We get to see all this happening in real time.  The kind of interoperability that's being talked about is not trivial.  Even a token swap with an ultimatum would have to give us at least 6 months to make a decision (due to the 13 week power down)
