Update: Our source just hit us with another pic, this time from the side -- it's after the break. We're also told that there's not one, but two NVIDIA GPUs inside --
Update 2: Our source just hit us again to say that it's two full-on NVIDIA GPUs -- sounds like a hybrid SLI setup to us, which is pretty wild. Wilder still, they say the MacBook and 17-inch MacBook Pro aren't getting refreshed tomorrow, which we find hard to believe, but we'll see when we see.
Update 3: John Gruber over at Daring Fireball, the first to accurately predict today's launch event, has confidentally chimed in with many more details. The button-less trackpad is indeed glass, and "is a button itself" which opens the door for a few hours of trouser-heated speculation about the trackpad doubling as a BlackBerry Storm-like display (Gruber doesn't say and it doesn't appear to be in that image above so don't count on it). Gruber also claims that none of the new laptops will reach the rumored $899 price point -- the part number spotted earlier seems to be associated with a new 24-inch LED Apple Cinema Display with DisplayPort according to MacRumors, not a low-end MacBook. To support this, Gruber says that the aluminum MacBooks will indeed be announced in $1,299 (2GHz, 2GB memory, 160GB disk) and $1,499 (2.4GHz, 2GB memory, 250GB disk) configs and will ship by the end of the week along with new 120GB HDD and 128GB SSD configurations of the MacBook Air. While CPU clocks will remain pretty much the same, all new MacBooks -- regular, Pro, and Air -- will feature the new NVIDIA 9400M GPU -- the 15-inch MacBook Pro (the 17-inch will remain unchanged albeit with 4GB of memory and bigger 320GB disk) will feature a second 9600M GT GPU making it a true graphics powerhouse as previously speculated. Lastly, the current 2.1GHz white MacBook remains in the line-up but will be cut to $999.
