Di Rupo announced an agreement on a Walloon government of MR, PS, and Ecolo.
Does this mean that a similar coalition can be formed on the federal level?
Short answer is yes, although they still fall one or two seats short but Défi and maybe CD&V would back them in, the latter needing a big portfolio.
Long answer is that it would require Open VLD to backtrack on their commitment to upholding a Flemish majority on the Federal level. They are in the midst of internal strife so no one in Open VLD has an incentive of backing any federal agreement.
There is still the idea touted of having to replicate Antwerp's coalition (Yellow-Red-Blue) if only to pass a budget and/or re-voting.
I think its a given that this one is going to be formed after long long drama and negotiations.
It wouldn't be atypical for Open VLD
