Sometimes, its tough to see the gap between sensor sizing only by reading a spec sheet. The photograph below will provide you a stronger sense of the sensor sizing in the W810 and A77.

Clearly, the two cameras have got different resolutions and different sensor sizing. The W810 with its tinier sensor will make getting shallower DOF harder and the Sony A77 will offer you greater detail using its extra 4 Megapixels. Greater resolution will allow you to crop photos much more aggressively. The younger W810 is going to have an edge in sensor innovation.
