This style of announcement is nothing new for Qatar, and the lack of detail fits the type.
They 'announced' they wanted to serve BHX and HEL for example, but then the elapsed time from that initial 'announcement' to then the formal announcement on both destinations separately was around 3-4 years IIRC.
So, I feel this forum shouldn't be getting into a frenzy just yet, as exciting as it may be, as I feel it may be a while to wait until the next set of details emerge.
