If you have played the demo, its like 7 min long, MAX.
But anyways, the pictures of gears of war 2 has clearly been polished, you can tell. When i play it its actually FAR from that "clear", and with the picture resolution so small it makes the game look better. Sony bravia 42" full hd if you think im sitting infront a 17" crt. Turn on killzone 2, look at the scenery, its amazing. The characters also look more "real life" in killzone 2, wich is a + in my book. Sorta "cartonish" look in gow2 (IMHO!). But in my eyes they are both worth the money, 2x good games. And gt5..no point in even comparing that game to anything out at the moment, its mindblowing in every aspect.
2 reasons for 360 sales.
Cheap arcade version, wich the mom buys for the kids.
And microsoft's wallet.
