Holy fuck, are we looking at the same stats? The ones that say Home Video Games brought in 33,949 million yen, while Arcade Operations and Games combined only brought in about half of that, 14,270 million yen?
Unless I'm missing something extremely obvious, such as a seperate category showing Profit per division or Cost per division, it seems that the situation is the exact opposite of what you just described. That is, unless you're just looking at lines instead of numbers.
To be fair, you could be talking about the growth in the Arcade sector being relative to the shrinkage of Home Video Game sales, but that's only impressive if you're looking at percentages, that is, Home Video Games going down 30% from the previous year and Arcade Games leaping 463% over 2003. But once you realize that HVG snagged 48,090 million yen in 2003 while Arcade Games only grabbed a pitiful 959 million yen, well, those percentages make a lot more sense.
Even then, there's no way you could consider the 4,069 million yen gain from 2003 to 2004 in the Total Arcade sector as "propping up" the "shaky console business" that sold 14,141 million yen less in 2004 than 2003. Not by a long shot, and don't forget, HVG is still bringing in over double the sales of the total arcade sector. And the bulk of the sales there are in Arcade Operations, not Games.
