Not sure if I'll maintain this as a weekly thing or not, but I thought it was interesting to look and see how many subscribers had preordered on various titles, just to gauge relative interest levels.

In general, higher preorders means higher sales, but not always. Licensed books like Anita Blake, Star Wars Legacy and Dark Tower won't sell that much higher than their preorders, at least at this point in their run, although Dark Tower in particular was a sales-off-the-rack monster early on. Green Lantern, Dark Avengers and Blackest Night Titans all benefit from huge interest in their crossovers.
The order numbers on Green Lantern and Batman and Robin are pretty much identical, and will more than likely generate strong shelf sales and eventually reorders.
Guardians and Nova are probably the anomalies for my shop, as I expect they're much lower on the charts than the others here at most stores across the country, judging by the sales charts posted on ICV2 and The Beat.
