Heres my breakdown
If the video was in rotation a month ago, and everyone was catching on to Techs sound cause remember, he's gonna be new to more people than we all believe, then I can say 61,312 units the first week. Gold in 9 mos.
Since its prolly not gonna drop before then, I'd say a good 24K the first week. Gold in 1.3 years
If the video somehow appears on MTV and BET between now and the release date, then I can 38,599 units... Gold in 1 year.
If Tech appeared on 106th & Park or TRL on the release date, then I'd say 83,787 units... Gold in 7 mos.
