According to the GalNet article today the Galactic Summit is supposed to begin today. My thought is that Odyssey was originally supposed to launch between now and about 3 weeks (based on summit length). Yes, it's been delayed, but I think it will still work out.
Anyway, here's the tinfoil hat part:
The galactic summit will be disrupted at a minimum, with a possibility of assassination of at least one or maybe more of the Powerplay Leaders at the summit. The blame would likely be laid against Jupiter Rochester and his breakaway Jupiter Division, having already started shooting back at the Federation in their star system.
In the turmoil and distrust caused by the attack the Superpowers will look for a way to start fighting on the ground. In desperation and out of mutual distrust of the other Superpowers, each will reach out to the only truly "neutral" authority in the Bubble – the Pilot's Federation.
I'm expecting that eventually there will be some planetary shootouts with Jupiter Division or whoever Frontier decides to paint as the antagonists. JD seems likely at this point given the breakaway plot via GalNet and events in-game, but it will probably grow to encompass multiple megacorps chaffing at Superpower rule (Sirius anyone?).
Ok. Enough tinfoil conspiracy theory for now.
