I'm also questioning the Samsung 7003 model.
I've been watching the Samsung models for about a year now. I own 2 samsung LCD LED tvs already and had my heart set on a UN55ES7500.
The price of the 7500 seems to be 'locked' at $2197.00 all over which leads me to believe there is a 'price lock' by Samsung vendors so they can 'under sell' other vendors.
While I was searching for lower price Samsung 7500 series TVs a 7003 poped up. First time in a year. It never existed before. The price seems way to low, I'm finding it at $1490.00 at a lot of stores. The fact that it's a 7xxx series makes me think that it has some or all or non of the features of the true 7500.
Does anyone know what the difference is with the 7003 model, how it came to be, and why it just appeared this month(December, 2012).
