This is probably true, but I wouldn't make a big deal of it. Based on the amounts, it helps smooth out the price change. Instead of an instantaneous $1875 hit in price, it was $500 more in November, $1000 more in (mid?) December, and if they drop the price by $1000 in January, it will be $1875 more in January (as compared to prior October pricing). So including tax affect, it's 3 smaller price increases instead of 1 larger increase.
If they do this, they should probably do it immediately on Jan 1 (or retroactive to Jan 1). If they drop the price after Jan 1 (without retroactive to Jan 1), anyone buying between Jan 1 and whenever the price drops will unfortunately be paying a higher price than they could have.
