That's worth knowing if you're intending to build a battery product.
I've been comparing the Teensy products with the Mega Pro, and for my intentions it comes down to whether I can afford 30 mA drain on a standalone battery with the Teensy vs the 3-5 mA on a board like this. Add in a Zigbee module to your project, and you have potentially serious battery life issues.</p>

The fuse settings you have used in your board file are wrong. The resonator is not being used. You have it set to use the internal oscillator. The internal oscillator has ±10% accuracy before calibration. The resonator is ±0.01%.
You have them set at:<pre><code>//Sparkfun Defaults
mega2560v.bootloader.low_fuses=0xE2
mega2560v.bootloader.high_fuses=0xD8
mega2560v.bootloader.extended_fuses=0xFD
</code></pre><p>They should be</p><pre><code>// Updated
mega2560v.bootloader.low_fuses=0xF7
mega2560v.bootloader.high_fuses=0xD8
mega2560v.bootloader.extended_fuses=0xFD
</code></pre></p>

Since this is a Pro version take a few liberties and add 3 pin headers (sig,+,-) for all the pins going down the side so we can connect servos and sensors directly. Or better yet just make a small board that just adds those pins that only plus into 6 or 8 pins. Also why not do some nice stuff like battery charger circuit and 3.3 to 5 switch able like seedstudio did. This would be perfect then.</p>

Though if that's bad, I think the upcoming Arduino DUE with it's ARM processor will have almost (if not more than)half the pins not broken out as it has the same pin layout as the Mega. It would be nice if there were little square SMD pads on the bottom of the boards so that we could make backpacks that could breakout these pins so that they could be used. :-|</p>

It would be nice to have a single hardware that can wake up based on time without having to add add-ons.</p>

It seems to indicate that there will be a Mega Pro Mini Version, Would this be the 5v version. Thats a teaser, cant wait to see the production model.</p>

OK, adding them might interfere with the shield connections, but they could at least be brought out to solder pads on the board. (There is at least one Arduino mega clone that DOES bring out ALL of the I/O pins). Maybe on the next board spin ... PLEASE!</p>
