I think it was the exact opposite. I think they had/have the intention of being very aggressive this time around.
1) Kaz says they'll wait for Microsoft to announce (bait).
2) Sony have their reveal date video come out of nowhere.
3) Sony have a well polished presentation with the ethos of the system as the focus.
4) They have been aggressively courting new partners for a while (Blizzard, Indies, Bungie etc)
5) The vast majority of the HW is mature in design and Sony have had developers working on PS4 for at least a couple of years.
6) The engines are mature, relative to PS2/PS3 timescale. Certain EU developers have been tech researching for PS4 for at least 2-3 years.
7) Going first has granted them a lot of good will from people all around the industry. They aren't playing catch up. They are the ones to beat now.
