In regards to game sales Halo Wars and Kill Zone 2 should be both guaranteed over 2 million game selling titles.
In regards to being console hardware sellers. Well Kill Zone 2 will be selling to people who already own PS3's and who have previously bought shooter games: Call of Duty games (COD 4: MW, COD:WaW), Resistance 1& 2, etc. The original Kill Zone on PS2 sold modestly and it received mixed reviews.
Halo Wars could be XBox 360's surprise console seller. Halob Wars will sttract RTS fans and people looking for something different on the XBox 360 and it could be the first stand out RTS console game. Rumour has it Diablo 3, and a possible Halo Wars sequel and a few other RTS games could be coming to XBox 360 as console exclusive in the future providing Halo Wars is successful from a sales perspective. Halo Wars having Halo in its name could help sell the game on brand name "Halo" alone could attract a couple of million buyers of the game.
With both XBox 360 and PS3 having some good games coming out in 2009 with Halo Wars Vs Kill Zone 2. It looks like the HD console war battle between XBox 360 Vs PS3 "Fight for Second Place" is intensifying and we all look forward to seeing how 2009 unfolds.
From a betting perspective my money is on XBox 360 to hang on for second place over PS3. Currently as of Jan 12 the XBox 360 lead is over 8 million consoles over PS3 in worldwide sales and that gap will continue to widen over 2009 unless PS3 price is dropped.
