Theft / Discounting Items - No Arraignment

My question involves criminal law for the state of: Georgia

My son was arrested 2 years ago on theft/discounting items at a small Mom and Pop type gas station.I bailed him out the following day.
I retained an attorney for him that week.The attorney sent a representation form to the courthouse .This was 2 years ago. Since then,there has not even been an arraignment ! The attorney,last week,told us that the other side have not even retained an attorney. The charge is a felony,because the items that were discounted went over $1000.
The manager and 3 other employees were also arrested about the same date.
The attorney said he is waiting for the other side to do something but they havent yet.
Question..is there a statue of limitations ? Attorney said no,,he said sometimes they throw non active cases out.
What can this Attorney do to move this forward ?

How can I get the case reviewed by the judge ?
Can the Judge issue a time line on this ?
My son just wants to get this over with and so do I.
Thank you for reading.

Your son's attorney presumably doesn't want to press the issue with a prosecutor out of concern that the prosecutor will respond by authorizing charges. Your son may not like to wait, but he made the choice to commit a crime - waiting without being charged, all things considered, isn't such a bad outcome for what might otherwise be a criminal charge and felony record.

Thanks for answering.I guess you have a point there.
