Have CA announced anywhere what their plans are for the total war series? I know warhammer is the 1st part of a trilogy of warhammer titles but are their plans either

1 - release warhammer titles annually for the next 2 years
2 - release warhammer and historical titles alternately every year
3 - release both a warhammer and a historical title for each of the next 2 years

Anyone know?

as much as im enjoying warhammer as a refreshing change I definitely still prefer historical titles.
