How should we improve our next multiple function Sensor Development Tool?

Looking for feedback for our next sensor platform project. Should it be a shield with all the sensors on it, individual sensor modules, or just a few modules with assorted sensors on them?

An overview of our latest sensor evaluation kit can be found here:

In working with sensors, I rarely need more than one type. I like to be able to put them directly on to a processor serial bus, I2C is often OK, but it depends on the speed and if I need to have well defined fast sampling times, I prefer the SPI bus.
Even if I need more than one sensor, for example, say some type of meteorological, or position sensing platform, I would prefer would them to be separate so that I can place them individually where needed. It also helps to have software libraries available for the relevant individual parts. Just my two cents worth,
cheers,
