There might be a delay because now EE seems to be CIC's priority but as per CIC's stated rules, your application would still be processed in CEC even if it was submitted a day before EE commenced.
You might want to consider EE along for faster processing, that is entirely your personal choice and i don't know how CIC would cater that. But fee would be separate for each.
However, in my opinion if you applied via CEC, then stick to it and be patient.
