Just tried a fresh install using "openSUSE-Tumbleweed-NET-x86_64-Snapshot20150309-Media.iso" downloaded just now which is newer than the one available to download on 2015-03-09 as detailed below. (so I guess a delay between release date and publishing) However the the warning about "Your computer does not fulfill all requirements for a graphical installation..." still happens. I am not convinced the problem is fixed.
