TCL's press release also mentioned two other series of step-up Roku TVs coming soon, the S3800 (32, 40, 48 and 55 inches) and S3850 series (32, 40, 48 and 50 inches) launching later in the second quarter. Again design is the chief difference, with the S3800 getting "a new ultra-modern design with a quad pedestal stand" (paging Samsung) and the S3850 getting "premium design with a metallic finish offered in gunmetal and an all-aluminum quad pedestal stand." Pricing for the S3800 and S3850 was not announced.
Also mentioned were the 4K TCL Roku TVs first announced at CES. They're still said to be under development for some unspecified time in the future.
