Is this a Pre-announcement leak for the D800?

4/6FPS (Native/Battery Grip)

Interesting...anyone know why the FPS would be higher with the Battery grip? Do they include some extra cache memory in there? Or does it provide a little bit of extra juice to 'overclock' something to get those extra 2 FPS? Or is it simply if you spend some extra money with Nikon, they reward you?

Yes - it's because it reverts to crop mode, giving an image size equvelant to a 15.3mp sensor, allowing to operate at the extra 2fps. Why it wants the battery grip to enable it is beyond me, unless it's because it creates a power drain when running at higher frame rate...

Yes! Beautiful cam! This guarantees the announcement of the MkIII very soon. The 5DIII will outmatch this. Canon isn't dumb. Expect higher mp's and feature-set. This will not be the Raw video cam and not 4K yet.

I almost never look at the Nikon Rumors site and have never read comments over there before... nasty bunch.

Yeah, those guys are really nasty to each other! The majority appears to be ready to trash anyone that dares to disagree - what opinionated & rude geezers!

... nasty bunch.

Very.  That's one of the reasons we try and run a tight ship over here.  Nasty may be temporarily amusing, but generally unhelpful, and particularly intimidating for new users.

Actually, the NR management are good people, but currently have a issue with the blog software.  It is almost impossible to moderate, delete comments, or ban users.  One day, they may get it fixed or get something different.

CR is able to easily remove inflammatory comments, threads, warn or ban users, etc, and they do this every day.

Once it gets officially revealed, we'll know for sure why it requires a battery grip to switch to DX mode and enable higher FPS...doesn't make much sense to me since none of their other full-frames need this!

I am sure the admin(s) are good folks, but they really need to update their software! Having so many jerks on their commenting on their forums is surely not good for business...

Agreed. They are a nasty bunch over there. Almost like the iFruitcakes...

Over-volting is not completely out of the question, but I wouldn't bet on it. If I had to take a wild guess, it would be to provide additional current to drive the built-in flash that fast? Does Nikon have any cameras with no built-in flash nor fixed grip (a la 5D)? Seems sort of silly, though. It's always possible it's just a marketing ploy.

  Perhaps overvolting could be out of the question since electronics are very sensitive to over and undervolting. While over "current" on the other hand could be a very possible reason. Power supplies rely on capacitors and regulators to steady the voltage supplied to the curcuits.

Under higher FPS, the regulators will drain the battery much faster as they demand more current to make up for lost voltage to charge the capacitors. With 2 batteries there, the risk is lowered, in this configuration they are run in paralell, i.e. 2x current, not in series , i.e. 2x voltage. Then again as Neuro says, it is a carryover form film days and they want to sell you a grip and batteries.

+1 to you for your efforts!

Didn't know that... so does that denote a limitation on the Expeed processor?
