Because Amazon's top seller list a complete waste of time when trying to track the success of one gaming product over another.  :p

26. WarHawk Bundle with Bluetooth Headset

73. Resistance: Fall Of Man

80. Madden NFL 08
83. Sony Playstation 3 Memory Card Adaptor
85. Ninja Gaiden Sigma

GRAW is out, Memory Card Adapter and Ninja are back.

Not a good day for Sony. PS3 is a lot lower than Wii (which is 2nd). Most of the games are also lower than were yesterday, its especiall bad day for Warhawk (26->36), also Ninja get out of the list.

97. Lair

Close to its release Heavenly Sword is going up pretty fast. Both Warhawk and Lair are losing its positions. Also bad position for Madden which can be out of list soon. PlayStation 80 GB and Memory Card Adapter are out of the list, so only 8 PS3' titles are in top 100.

Not a good day for Sony, are hardware is down, the positive thing is quite high position for Heavenly Sword, Lair and Madden did a little better than yesterday.

56. Blu-ray Disc Remote
57. WarHawk Bundle with Bluetooth Headset
67. Madden NFL 08
73. Lair
99. Resistance: Fall Of Man

PS3 still doing extremlly bad and the list haven't been that short for a while. But HS got almost to top 10 and this is one optymistic thing. Warhawk position seems to stabilize, Lair (102th) and PS3 80gb (101th) were very close top 100.

17. PlayStation 3 (60GB)

59. WarHawk Bundle with Bluetooth Headset
69. Madden NFL 08
78. Resistance: Fall Of Man

 if you actually look at some of the titles in the top 100 right now you would realize half of the games that should be in it have been pushed out due to items that have been marketed down and like 8 products are halo 3 related. 

HS made to top 10!

10. Heavenly Sword
11. Wireless Sixaxis Controller
13. PlayStation 3 (60GB)
37. Blu-ray Disc Remote
53. WarHawk Bundle with Bluetooth Headset
71. Resistance: Fall Of Man

Hs still in top 10 but its not helping hardware sales.

10. Heavenly Sword
12. Wireless Sixaxis Controller

43. Blu-ray Disc Remote
53. WarHawk Bundle with Bluetooth Headset
68. Resistance: Fall Of Man
83. Madden NFL 08
90. Lair

Only six positions on the list and PS3 60 gb out of top 25. It looks like HS isn't moving hardware at all.
