Roughly two years dev time for most games since a dev kit close enough to definitive HW is available, this should mean a Q4 2014 launch.

They've had the graphics card pinned for the PS4 a while now so they've been developing already. These new dev kits are additional clarification on final specs and branching out to more developers who may or may not be aiming for launch.

Yes, this could make Q3 2014 another option. Q1 and Q2, even if possible, wouldn't be a good choice, and Q4 2013 would still be too early and allow it to have only rushed or little games and ports at launch, possibly ruining it, a risk Sony cannot take.
