In many cases, it can be difficult to visualise the gap between sensor sizing merely by checking technical specs. The graphic here will help give you a more clear sense of the sensor sizing in the H90 and DP2 Merrill.

As you can tell, both of the cameras posses different resolutions and different sensor sizing. The H90 due to its tinier sensor will make shooting shallow depth of field more difficult and the Sigma DP2 Merrill will resolve greater detail utilizing its extra 3 Megapixels. Higher resolution will also enable you to crop shots somewhat more aggressively. The older H90 is going to be behind in sensor innovation.
