I reached out to the company and was told, "The Chicken Selects will make a national return in early March and be sold as an order with 3 pieces. We look forward to bringing back this customer favorite made with chicken tenderloin."
The "new" Chicken Select Tenders feature white-meat tenderloin strips, lightly breaded and seasoned.
Chicken Selects were McDonald's fried chicken strips offering and were discontinued back in 2013 along with the Fruit & Walnut Salad.
Update 3/9/15: The new Chicken Select Tenders are sticking around through April 20, 2015 here in Southern California (it may vary in other markets).
