The prime mode for 2m eme is now JT-65; CW has been largely replaced.

Hi Ed, KL7UW
I am anxious about that because even on EME very soon nobody will be able to use by hand a CW key and copy Morse Code by ears.
I am sorry because I like very much the CW sound in my ears.
CW is like music for me and after to eliminate the Radio Officers over the ships we radio hams we actually should be the last frontier for the CW existence.

You can still do eme on CW, just it will take a bigger antenna array and 1000w to be heard. JT-65 enables a station with a couple 10 element yagis or one longer yagi and 150w the ability to do eme on 2m. That is a huge attraction.
One takes about $5,000 and the other $500-800. You see the 10-dB advantage applies to the cost as well! ;-)
CW is still prevalent on eme at 1296 and above. I still hear plenty of CW around 14.020. It is the main mode used on LF and MW. but digital modes are demonstrating they are superior in weak-signal as well as emcomm.
WSPR on 10-MHz has been copied at 120 microwatts.
