hi tkc,
my billings guess is $10m or so, like the inflow.
but i think they will report revenue of $8m due to the little bird order (which defers the income to 2013).
i am not going to spend the time to figure prepaid maintenance on old large orders etc. i don't think it is a huge number.
i think the only major order still in the non-maintenance revenue pipeline is BP.
so if there's a $2m order at the end of q4, which was paid upfront, that will just about replace BP for 2013.
