Highlander was announced and done before the flea.
What is your reasoning for them to actually not give it to us after Jager?

Roland was posting based on the order of the reveal announcements; the Flea was announced on Sept. 26 while the Highlander was announced on Oct. 17.
Though, the Devs did have the Spider (a Light 'Mech) jump two places, to between the Stalker (an Assault 'Mech) and the Trebuchet (a Medium 'Mech).
As I stated previously, there is a possibility that the Highlander might be moved ahead of the Flea (or, alternatively, the Flea might be moved to after the Highlander - the end result is the same) if the Devs wish to preserve the weight progression.
However, there is also a possibility that the Devs may choose the announcement order over the weight progression, in which case the Flea would appear in-game before the Highlander.
