The Seoul office stopped receiving application on January 28 this year. So if you filed back in October, your file is actually being processed in Seoul and not Manila. I would imagine they are eager to push all the apps through to close them out, so you should be getting some feedback any day now.
When it comes to being approved, lots of it is pure luck and dependent on how the VO is feeling. VOs are expected to maintain a certain level of approved and rejected applications. If they haven't rejected one in a very long time, they'll need to scrutinize more to find one they can possibly deny... so just need to hope you're not one of those! In total though the Seoul office approves 95% of all applications, so you shouldn't have anything to worry about.
