That might be part of the reason we were all pissed at the endings: we were all expecting an ME4, whereas BioWare was expecting to burn the house down on the way out.

Regardless, that's an excellent point; I'm guessing that they'll need to make some choices canon. The only way to really import EVERYBODY's Shepard is to have the geth, quarians AND rachni not show up at all, which would be stupid. Any canon should sort out the whole ending crap too - the Reapers are gone/missing, but EDI and the geth aren't.
