I purchased the 2010 i7 a few weeks ago. The total cost was $2635.66
I took it back when I found out about the refresh.
I purchased the 2011 i7 today with the 2gb 6970 and it came to $2612.66!
So yes, the prices have dropped! But in my case I ended up spending around the same. To upgrade to the i7 this time around was 20 bucks cheaper and the imac was $1999 instead of $2050 or $2099 Can't remember what it was before.
