Pre-sales of LE and add Pro sales (assuming 500) have surpassed IM right out of the shoot.
Prem sales will kick in as Pro owners love it enough to sell and upgrade and those waiting on the fence fall into the buy spree. Yes I do believe one more update will show those that doubt SR will be convinced.
I do believe there are a lot of would be owners waiting on code or the LE to show what it "could" become.
I also believe there will be a second wave of purchases after Christmas. Some people feel guilty about spending so much on a toy for themselves prior to Chirstmas....all bets are off come tax return time lol.
