Presumably, the 17" MBP is the least popular in terms of overall sales, right? (Someone correct me if I'm wrong). So is it really that surprising (or revealing of a refresh) that third-party vendors would be running low of this particular model? Wouldn't a better indication of an imminent refresh be if we noticed a significant drop in 13" and 15" MBP inventory? For the most part, I've only been seeing inventory drops in the 17" models.
