Nash,
Back in the day when gaming magazines were still dominating the PR aspect of the gaming industry, the quarters were calendar quarters starting with January.
Thus if a game were coming out "second quarter" it meant April-June. I'm pretty sure HT is using that convention, rather than a tax year or something.
Well Beet1e, I think the majority of the workload is graphics engine and graphics engine related. I seem to remember something like an programming an automated mission planner is easy but the graphics engine takes a lot of time.
