Keep in mind, the weight of an ILC will differ dependant on the lens you are using at that moment. Following is the front view physical size comparison of the TG-850 iHS and the DP2.

Considering dimensions and weight, the portability score of the TG-850 iHS and DP2 is 91 and 86 respectively.

Normally, its hard to visualise the gap in sensor sizing simply by viewing technical specs. The visual below should offer you a far better sense of the sensor measurements in the TG-850 iHS and DP2.

As you have seen, both cameras offer different megapixels and different sensor sizing. The TG-850 iHS with its smaller sensor will make shooting shallower depth of field trickier and the Olympus TG-850 iHS will provide you with more detail using its extra 11 Megapixels. Greater resolution will also enable you to crop pics a little more aggressively. The more recent TG-850 iHS will have an advantage in sensor tech.
