From Silent Hill Historical Society:
Today, Konami Digital Entertainment, Inc. announced that online patches for both Silent Hill Downpour and Silent Hill HD Collection are currently in development and will be released soon.
Understanding the issues some users are experiencing, development teams are currently creating online patches for both games, which will fix the frame rate issues, the audio-synching in Silent Hill HD Collection, and the Auto-Save issues in Silent Hill Downpour. Players have voiced their concerns, and solutions to these issues will be fixed and launched in the coming weeks.
Patches for Silent Hill Downpour and Silent Hill HD Collection will be made available on both XBOX®Live Arcade and PlayStation®Network.
Finally! It's good to know that there will be support for these technical issues, rather than ignoring them and not acknowledging them. This is definitely a step in the right direction for Konami.
