Saleswise and according to this very site, the Final Fantasy 13 games are currently standing in 7th (XIII, PS3), 12th (XII-2,PS3), 15th (XIII, 360) and 32nd place (XIII-2, 360) out of a list of more than 100 FF titles.
If you combine the sales of both PS3 and XBOX, both Final Fantasy XIII and Final Fantasy XIII-2 would be in the top 10 best selling FF games so far, in 4th and 10th positions respectively.
So yes, I'd say they got the memo, and the memo said 13 makes money.
