More often than not, it is difficult to visualize the contrast in sensor sizes merely by seeing technical specs. The image below may give you a better sense of the sensor sizing in the W570 and A58.

As you have seen, each of the cameras offer different megapixel count and different sensor sizes. The W570 with its smaller sensor is going to make shooting shallow depth of field harder and the Sony A58 will show extra detail using its extra 4MP. Greater resolution will also make it easier to crop images a little more aggressively. The more aged W570 will be disadvantaged in sensor innovation.
