They are finally here. Webtatic now has released a Webtatic EL7 Yum repository for RHEL and CentOS 7.0.
The packages that are included in this release are:
The Webtatic EL7 repository is accessible via https by default, although you can alter the /etc/yum.repos.d/webtatic*.repo files to change to http if needed.
Additionally, the EL6 and EL5 repositories can also be accessible via https, however will default to http due to potential issues in earlier RHEL/CentOS 6.x and 5.x releases. The version of the 'openssl' package determines whether https will work.
The reason for the delay in getting EL7 released was due to the general development and testing frameworks I use to roll out packages being slow to update for CentOS/RHEL 7.0 support, some of which I helped contribute support for.
