Update at 11:15 p.m. PT: The iPad Mini will get a refresh in the third calendar quarter with a Retina display, NPD DisplaySearch predicted late Sunday.
This is an update to information that DisplaySearch provided earlier Sunday.
"We see two refreshes coming. One [with a Retina display] in the second half of this year, then one in Q1 [first quarter] of 2014," analyst Richard Shim told CNET late Sunday night.
"The Q1  device will have a Retina display plus an updated processor," Shim added.
Earlier Sunday night, NPD stated that the first iPad Mini with a Retina display would appear in the first quarter of 2014. That will actually be the second refresh, according to NPD's updated prediction.
It's not clear yet which display technology will be used. One of the candidates is LTPS, or low-temperature polysilicon -- the same technology used in the iPhone 5.
