Apple Bug Report (Apple's Response Time?)
There is no easy way to tell how/when/if Apple acts on your bug report. I have filed quite a few bug reports during the last years. Some still seem to be unchanged since I created them, some got closed silently and there is only one where I ever got notified that the fix would be in the next OS X release.
So basically you filed the report, now just ignore it :-)
Additionally, you should file your bug on Open Radar, that is a community maintain website who tries to keep as much reports public. A radar basically contains just the same information you report to Apple.
Note that, usually OSX/iOS developers ask for help regarding concrete radars, this is because "we suppose/believe" that if lots of people reports the same bug, it will be fixed soon. It's a common practice to report a bug on Apple bug tracker by just copying the radar report.
