Earlier this week SanDisk announced that their new 1TB SanDisk Extreme MicroSD UHS-I Card will be available in April 2019 for $449.99 with an online form to reserve one now for those with a smartphone, tablet or other mobile device that supports the massive storage capacity! 
Competitor Micron also announced this week their c200 1TB MicroSD card will be available in Q2 2019, although they haven't confirmed exact pricing just yet.
Back in January at CES 2019 manufacturer Lexar unveiled their 1TB Lexar Professional 633x SDXC UHS-I card which is available now for an MSRP of $499.99.
Personally I'll be going with the SanDisk when I get a mobile device that supports 1TB, as my current smartphone has a limitation of only 128GB on the MicroSD card external storage capacity... however, by that time many smartphones may include 1TB Embedded Universal Flash Storage rendering MicroSD cards antiquated in general.
For those who missed it, this will be the culmination of my quest which started with KODI, migrated (briefly) to Mobdro and currently resides with utilizing Free Online Streaming Sites to grab my favorite movies and TV shows to watch without a WiFi connection, without paying for services such as Amazon Prime, Netflix or Hulu and without carrying around a Western Digital EasyStore or Passport... minimalism FTW!
