Alright I'll just analyze the titles that went platinum during the holiday season and then predict for the future:
360
Throughout its life cycle, 360 has been continuously known as a software beast. It has attach rates that are unheard of for any other console. Even after losing first place in the console wars in summer 2007, the software numbers kept rolling in. Holiday season 2008 has been no slouching moment.
Going into the holidays the 360 had 50 million sellers. This was the week before Black Friday or the week ending November 28. By the week ending January 3rd, 2009 it obtained 13 platinum sellers to get to 63:
Lego Star Wars II: The Original Trilogy
Need for Speed: Undercover
Soul Calibur IV
Lego Star Wars: The Complete Saga
Farcry 2
Left 4 Dead
Saints Row 2
Rock Band 2
Guitar Hero: World Tour
Sega Superstars Tennis
Fallout 3
Kung Fu Panda
Lego Indiana Jones: The Original Adventures
Now a few were games that had been selling for awhile that just made it over such as Soul Calibur IV and both Lego Star Wars. 3 of course came as a part of the recent bundles which is Lego Indiana Jones, Kung Fu Panda, and Sega Superstars Tennis. But most were games that had just recently released that showed their early selling power. I had originally guessed that 360 would have 61 million sellers by the end of the year but Farcry 2 and NFS: Undercover made that prediction a little off. Either way, 360 had a great year for new additions.
But of course it won't stop there. Not only did it add these titles but it has set up a few other titles to go platinum in within the first 3 months of 2009. These titles include:
Ninja Gaiden II
007 Quantum of Solace
Midnight Club: Los Angeles
Prince of Persia
Within the next 12 weeks I'd suspect that those all go platinum. Sonic the Hedgehog, Burnout Paradise, and Dead Space also have a good shot. Sonic, however, probably already is platinum if it had up to date sales in the others category. I'd suspect the same of DIRT, The Orange Box, and Scene It: Lights, Camera, Action.
For the rest of the year expect games such as Mortal Kombat vs DC Universe, GRID, WWE: SvR 2009, PES 2009, Lips, Banjo Kazooie: Nuts and Bolts, and Endwar to all make platinum status as well. There are a few others that have a shot but I'll wait for more time to assess them.
Along with that new releases in the next 3 months I expect LOTR: Conquest, Street Fighter IV, Halo Wars, FEAR 2, Resident Evil 5, Splinter Cell: Conviction(if the release date stays), and The Godfather II to all go platinum eventually.
2009 will be no slouch in platinum sellers for the software giant that is 360. As the userbase grows and becomes more settles attach rates can only increase and so will the platinum games. I won't predict when it will hit 100 but its got an inside shot to do it within the next 12 months.
