2800Mah with out the need of a extended backing!!!!!

I find it very hard to find that much juice in a small battery.

In any battery technology increased capacity =increased size. There is no mystical, magical way around this.

Uh, no.
There is constant push to increase what a battery can hold without increasing size. Go see what variety there is in rechargeable AA batteries. Heck, just look at the link I posted previously.

However, you don't typically get that much of a gain over the competition or without a complete formula change. That would have not only made headlines, but also, would have a nice big brand name attached in order to capitalize on it, or Sony or Panasonic would have jumped on it and bought it long before it ever reached market.

The difference in capacity with ni-mh technology in standard sized batteries is based more on costs, not on any technological differences. The large difference in capacity between aa batteries is due to meeting price points, not any particular innovation. The good, better, best model. Li-ion technology follows the same rules, you can buy the best, ie: oem and get the most power for a particular package size. Cheap no name Chinese batteries claim greater power in the same form factor but testing proves this false. Until a new technology comes to market we must follow the rules for current high capacity batteries, size=capacity.
 
Yes, with newer technologies.

In the example of NiMH AAs, the last "old" gen regular NiMHs were getting pretty decent in terms of capacity. Some were getting close to 3000mAh. Then, the advancement came in the form of the eneloop et al batteries, that are around 2000mAh but have very low self discharge. Really quite excellent since I rarely use my digital camera, and every time I did before, the batteries would be dead or about dead.

We went from regular li-ion to li-poly for our current higher density batteries. But again, with refinements to the same technology, there won't be that dramatic of an increase. And it sure as hell won't be from a $3.75 shipped battery :)

Yes technology is improving battery capacity but not at such a high rate that you could buy a legit 2800 batt for $3.75.

Actually this is combining 2 half truths, Li-Po technology has not improved in any significant way in over 3 years, all the while especially because of Chinese government subsidies the price per mah has dropped by almost 100 fold in the same time frame. So buying a 2800 mah battery for a few bucks is near at hand, while increasing the capacity by over 50% without a similar increase in size is not.
