Honestly, for the most sought after models (read: samsung evo), i think that is a bit too optimistic. But for the drives that do not have the marketing campaign behind them that Samsung definitely has, i'm thinking 512GB may fall to $125ish. The Evo is in so much demand that i do not expect to see a 512GB $100 unit on Black Friday. But it would be great if you are correct.
Oh, and i bit on this Mushkin, though I had been wanting to hold out for a 1TB Evo. A 1TB Evo may dip to the $250-260 range on Black Friday, but I think it will be months before that becomes the common price.
