I understand both M1 + M2 are under construction right now, since the 2 towers started sales well before the market tanked and achieved the required sales %
however, the same does NOT apply to the third tower ... Metropolis (aka M3) which was launched just ~3 months before the world fell apart in Fall 2008
you are correct CoC ... the buildings shown under construction are in fact M1 + M2 in the Metro Place complex (phase 1+2), whereas Metropolis = M3 (phase 3) has not started constructed yet
