The Landing Page for the Media Creation Tool has not been updated yet however the direct link to the Windows 10 Version 1903 Media Creation Tool is now available:
The iso images are larger than 4.7 gigs after 1803.
There are still "issues" with USB3 devices in general but I do not know why.
I use OEM System Builder DVD of 1809 with an external USB2 Blueray drive and it works on everything from 2006 machines to my new laptop that was built Feb 24, 2019.

It appears the 1903 Media Creation Tool gives Windows 10 Version 1809 V2 (Build 17763.379) isos and not Windows 10 Version 1903 (Build 18362.1) isos like one might expect...
The Direct Download Links call these Windows 10 version 1809 V2.
Up to 1803 works with regular dvd.
1809 64 bit iso's require a DUAL LAYER DVD
because they are larger than 4.7 gigs.
Burning any DVD its recommended to burn at 1X or 2X or 4X max.
8X and faster creates non reliable disks.
1803 get now or forever hold your peace
1809 V2 will also likely go away

Microsoft have removed the Windows 10 Version 1903 Media Creation Tool from their server... It looks like Windows 10 Version 1903 will be released in May at some point.
The links Speedstep posted are time limited... they have 24 hour tokens which will expire, after which they need to be regenerated. However it should be noted that the direct download links for all languages and all older versions of mainstream Windows 10 Builds are available on Microsoft's Servers. You have to however use a third party utility the Windows ISO Download Tool to generates the 24 hour time-limited download links:
They added a lot of stuff.
The original 1809 was 4.9 gigs.
The V2 1809 is 5.2 gigs.
Thats 300 megs of extra stuff.
The one with the most stuff before he dies wins.
I don't mind it being larger however the install.wim exceeding 4 GB in the direct download links is problematic for making a FAT32 formatted USB. They should split this into <4 GB files.
