The tides are definitely shifting, you get why Canon is making this move but I'll still be happy with my existing EF lenses for a while yet I think.

Don't expect new EF lenses – Canon confirms plans to focus development on RF-mount optics for the Canon EOS R
Canon has confirmed that it is focusing development on producing RF-mount lens for its full-frame mirrorless system. As it stands today, while the EF mount for DSLRs is still supported, there won't be any new EF lenses unless they are demanded by the marketplace.
The news comes as the company celebrates the launch of its new flagship camera, the Canon EOS-1D X Mark III – a camera that, like all Canon's full-frame DSLRs, can only use EF lenses.
“As you know, last year we launched the RF mount and EOS R system," said Richard Shepherd, pro product marketing senior manager at Canon Europe. "To date we’ve launched ten critically acclaimed lenses, and as it’s a new system we plan to continue this, launching more RF lenses while still fully supporting the EF lens system. And of course, should the market demand it, we are ready to create new EF lenses. But for now, our focus is on RF.”
