LotSB was like 1.5 months between announcement and release.
As for quarters, generally Q3 means the 3rd quarter of the year, which is July - September. When companies refer to quarters however, they're usually referring to fiscal quarters, and their fiscal year may or may not line up with the calendar year. Also as others have said IGN is just speculating and so them writing "Q3" doesn't actually mean anything.
I'd say IGN are just playing it safe with a Q3 timeframe. If they say Q3 people are just like "Meh, yeah, whatever IGN." If they were to say Q2 however, and then the content actually doesn't come out until after July, then everyone rises up in flames against IGN, lol.
Personally I don't think it's going to be that long though. If I were a betting man I'd say near the end of April to mid May. One week of the teaser screenshots, official announcement, more development, trailer and then one week of Cerberus daily news to come me thinks.
