Most people don't read patch notes, so there's still some profit to be made if you're quick. 100 Frozen Orbs will translate into 100 Frost Loti. On my server 1 Frost Lotus sells for 70g. If I was quick enough I could end up with close to ~3500g in my hands (I'm leaving room for error in case they don't sell as much).
Even if the price did drop, it won't drop to less than 20 - 30g, I assure you. That's still a decent 3000g from them. You can easily pick up Frozen Orbs in heroics, and off the auction house for a steal (Assuming your server hasn't caught on) at 5g. Each Frozen Orb collected this way has a 25 - 30g profit assuming you trade them for Frost Loti.
Ofcourse you can make some money, but it totally depends on the Frozen Orb price on your realm. On my realm, they are at 15-30g each righ now, but ofcourse, on some realms they maybe go for 5-15g each, the thing is, the prices will drop down and you wont make any big profit, belive me, you'll detect it. You should to be honest just sell to others that buy them above the price you bought them for.
