The folks at Laptoping spotted a couple of those listings, both for systems featuring the same Core i7-2630QM processor. One, a 15.6" Gateway machine, is listed at NextDayPC.com for $852.94. Another, a Lenovo laptop with the same display size, is priced at $1,138.35 at Provantage. Neither e-tailer quotes an availability date, but if the listings are up already, I don't expect it'll take too long for those notebooks to make it onto UPS and FedEx trucks.
Gateway and Lenovo aren't the only firms getting ahead of themselves, by the way. As Engadget points out, a page on HP's website details specifications for a Pavilion dv7 notebook that also includes the Core i7-2630QM. That particular listing tells us a little more about the CPU, namely that it has a 2GHz base clock speed and 6MB of L3 cache.
