Will hyperspace fights be initiated in a similar fashion to the Trade Lanes of Freelancer, or warp destabilization in EVE? Pirates can knock out a section of the trade lane in Freelancer, forcing ships to drop out of it and wait for it to become operational again or try and flee to the next section of the lane to get back into the slipstream. In EVE, specialized Interdictors can drop warp disruption probes that destabilize the warp bubble of a ship currently in warp, dragging it out of warp in the process. Though the effect of dragging the ship out of warp can cause it to slingshot many kilometres before coming to a stop, if it remains close enough to be affected by the probe still, then the ship is left unable to warp away. This also goes for the group using the disruptor probe, they cannot warp either, nor can the Interdictor that dropped the probe. Similarly, a Heavy Interdictor can mount equipment that allows it to become the probe, projecting it's own interdiction bubble.
TL:DR
Will hyperspace fights happen IN hyperspace, or will ships be dragged out of hyperspace to fight in deadspace?
