Infinity Ward's Rob Bowling has posted on his fourtwozero blog, a list of the various fixes on the way for Call of Duty: Modern Warfare 2.

The majority are hack fixes for the PC crowd, but some will be coming over to the PS3 and 360 version too.

We've listed the PS3 and Xbox 360 updates below:

• Care Package, Emergency Airdrop, and Sentry Gun marker grenades sprint speed normalized.
• Sentry Guns: Improved placement detection, preventing cases of Sentry Guns inside geometry.
• Model 1887: Bling using Akimbo and FMJ combination now has same range and damage as non-Bling Model 1887s.
• Improved player collision removing cases of getting into geometry and ‘elevators’. 
• Fix to prevent various XP hacks, including the prevention of obtaining negative XP.

The patch will be coming shortly after the PC one, which is available now.
