Ultrawide Thunderbolt Monitors

Any road map for Thunderbolt Ultrawide monitors? We've been trialing the U3818W but need Thunderbolt on our monitors so we can get rid of the docks. If you guys can make an Ultrawide (preferably 38") with a few Thunderbolt 3 ports and the dock.. I would buy about 5000 for my firm. Just sayin'...
