The rumor is that Canon will have a price increase in the US on February 1st, 2011 due to the weak US dollar. Canon will also be discontinuing all current A series point and shoot cameras on January 5th, 2011 (expect new p&s camera announcements during CES 2011). The SD1300, SD1400, SD3500, sd4000 models will be discontinued on February 7th, 2011 and will also be replaced.
