With the worrisome state of the global economy, it's not the best time for Sony's PlayStation 3 - the most expensive of the three home video-game consoles - to be playing catch-up. But Sony executives have good reason to be optimistic about 2009, and it boils down to one word: software.
Sony has the most impressive roster of exclusive games this year (although, to be fair, Microsoft and Nintendo haven't shown all their cards yet). The blitz begins this week with the dazzling first-person shooter "Killzone 2." After that, the PS3 release calendar blends original titles like "Infamous" and "Heavy Rain" with much anticipated sequels such as "Uncharted 2: Among Thieves."
