New features in these models include a new Touch Panel LCD with an advanced tracking feature, enhanced image stabilization, and an all-new HD-to-SD Downconversion feature (in some models) that allows video to be easily uploaded to the web or burned onto DVDs. Some models are also compatible with Eye-fi SD Memory Cards, allowing for wireless uploading of video content.
Canon also says that their HD CMOS Image Sensor and DIGIC DV III Image Processor have been improved to reduce noise under low-light conditions and deliver more faithful reproduction of purple and blue tones.

VIXIA HF S-series
All three new HF S-series models record 1920 x 1080 HD video and feature a 10x Lens and a Canon 1/2.6-inch, 8.59-megapixel CMOS Image Sensor. They also sport the new 3.5-inch High Resolution (922,000-dot) Touch Panel LCD screen and improved Image Stabilization.
The VIXIA HF S21 viewfinder appears to be different from the one in the S20 and S200, with Canon promising "a reliable viewing environment when shooting in bright outdoor conditions."
The new models will be available in April.
