The thinnest 15-inch laptop "on the planet" is coming tomorrow, costing a measly $999, according to the Wall Street Journal. In a profile of Dell's recent history and forthcoming plans in the consumer electronics market, the financial paper twice makes reference to an ultrathin, $999 laptop that is set to launch on Tuesday of this week. Pairing that intel with the abundance of leaks surrounding the slinky 15.6-inch XPS 15z -- including a Michael Dell tweet promising it's "coming soon" -- leads us to the conclusion that we've finally gotten ahold of the price and date for Dell's next big thing. Interestingly enough, the WSJ article goes on to say that Dell had canned a similar set of slim laptops earlier in the year, which might give us greater hope for the quality of the 15z -- it survived where others didn't.

Other disclosures in the piece include a quote from Michael Dell, saying that he "didn't completely see" the tablet boom coming, which might explain why sales of his company's Streak tablets have been low enough to be described as "immaterial." There's also a discussion of the abortive Zing music service and related MP3 players that never were, but you'll have to hit the source link to learn more about them.

Update: As further evidence of the 15z's imminent release, the tease has turned into a show with a video that fully reveals its slimline chassis and declares that the new Dell packs the Streak's Stage UI as well. [Thanks, Ishai and Ming Han]

Update 2: And now we have the answer to our headline question: yes.
