None of the newer APS-C Canons are going to be a big improvement in image quality. Canon's sensor tech has been roughly the same for the past 5-6 years.
If you want a big step up in sensor performance, go full-frame or get a Nikon.
That said, for product photography in controlled lighting, the camera body honestly doesn't matter all that much. The lenses are much more important. Depending on what kind of product photography you do, it could be much more worthwhile to invest in a Tilt-Shift lens or lighting setup over a newer camera body.
That is simply too generic an answer, and I would like to make some observations.
Comparing the XSi to any of the newer crop bodies would show:
- AF is better and faster now (impacts IQ)
- Availability of micro focus adjustments (impacts IQ)
- Metering is new and improved and is a bit more accurate (impacts IQ)
- Burst and fps are pretty darn good at least on a couple of the newer bodies, so if you are looking for just that one shot amidst action, the XSI won't deliver as many keepers (relates to IQ, or at least to the extent of keeper rate)
- A ton of other new and improved features that could really enhance the photographic experience, and if a photographer is confident of his equipment, and his equipment gives him more tools to be more creative, then that is good (relates to IQ, or at least to the extent of keeper rate)
- Optical wireless flash control, and as we know, light is everything in photography, so better placement of flash controlled by the camera at no extra expense in attachments is a good thing (impacts IQ)
- Ergonomics like size of body, changes in button placement, touch screens, tilt screens, etc could enhance the shooting experience as well.
- More resolution allows flexibility in processing.
- Better in camera JPG engine, so perhaps less time during post processing
So are any of these big improvements in sensor tech? Nope, but the entire combined package, depending on what model you look at in today's crop landscape, is a big improvement overall.
"Sometimes the quality of a photo isn't really dependent on the sensor tech, but the culmination of equipment flexibility, function and feature, photographer's enjoyment and experience with his/her equipment, quality of glass used, light, and heaping pile of creativity and vision." - Teamspeed circa 2013
