Can someone please provide me with a list of sensors on the create 2? I am hoping to get one soon, but want to be sure it has ultrasonic sensors and not just bump sensors before I do.

Many good questions generate some degree of opinion based on expert experience, but answers to this question will tend to be almost entirely based on opinions, rather than facts, references, or specific expertise.

The Roomba does not have ultrasonic sensors, but it does have quite a few infrared proximity sensors. The Open Interface Spec calls it the "light bumper".

Package IDs 46-51 (pages 30 and 31) describe the different light bumper IR sensors. They return a 12 bit number (0-4095) which will roughly correspond to distance to an object. However it is highly dependent on the object's material. The "light bumper" packet (45) contains a binary version of all the light bumper sensors together. I don't know what threshold is used for this.
