DICE: Some Frostbite Games Will Require a 64-bit OS
If you're still gaming on a 32-bit OS come 2013, you won't be playing some of DICE's biggest releases.
DICE has made considerable improvements over their Frostbite engine with the release of Battlefield 3. Consequently, these improvements and enhancements demand more power from your PC. According to Johan Andersson, rendering architect at DICE, some Frostbite powered games in 2013 will demand a 64-bit operating system.

Currently, PC gamers can run popular titles fine on a 32-bit OS, which makes convincing them to switch difficult. The real benefit gained from a 64-bit operating systems is that it can address 4 GB's or more of RAM. He states that the main driving force behind this requirement is larger Virtual Address Space (VAS) and RAM access.
Johan Andersson suggests that if you do not currently own a 64-bit OS, the release of Windows 8 is a good opportunity to upgrade.
however, 64bit is a must for most gamers anyways. even though most games aren't written in 64bit it's definitely better to have a 64 bit OS just so it can have allocate more ram and have enough ram for the OS and the game rather than swapping from a pagefile.

Heaven forbid we have to start phasing out consumer 32-bit o/s'. Its only 2012 after all
Thats a lie, win8 has better performance in games due to being less resource intensive
Though i think most people who use 32-bit OS's are just people who don't really understand or care about what any of it means, they'll continue running there 32-bit copy of XP as long as it opens of Microsoft Word. There is no real incentive for most people to move up to a 64-bit OS, hence i think that 32-bit OS's will still be large use into the future.
It is up to Microsoft and other software devs to push foward and start creating more 64-bit orented software.
I think you're a bit off as to the year - consumer-level 64-bit processors have been available since 2003 (look up the Athlon 64). Win XP x64 came out in 2005.
you really know nothing about windows 8 do you kid?
On the other hand, I agree that there is almost no reason for regular end-users to run 32-bit anymore. Although... chances are if you're still running a 32-bit OS in 2013, your machine is ancient and won't run these games anyway. So it's really a non-issue.
As a general rule, 64-bit operating systems (and corresponding hardware) make access to more than 4GB of RAM easier - they are not, however, required. Doesn't anyone remember protected mode? LOADHI, farptr, and PAE are inconvenient, but workable.
Absolute 64-bit saturation means better utilization and development for the additional resources, helping make applications better.
Rejoice!
