Haestrom is really the ONLY foreshadowing for a Dark Energy plot. And my point about the Signal Tracking was how the AI explains his history and origins, as well as his reasoning for not trusting organics - The two are diametrically opposed, and seem completely unable to coexist for long periods of time. The Rogue VI on the moon is a similar example, and obviously the geth are the meta example. Basically any time a true AI comes into being in Mass Effect comes into being it opposes and is opposed by organics.

If the route of the Dark Energy plot had been used then the same complaints would have been raised. The only real foreshadowing of this plot is in the SECOND game of the trilogy in an OPTIONAL mission, making the idea come even more out of left-field than people suggested the Synthetic idea did. That isn't to say the idea of increasing use of dark energy based technology having a negative effect upon the universe isnt a plot without merit - it is a viable plotline - but it shouldnt be the main reason behind the Reapers, especially as that outline still fails to resolve that idea...
