Strictly speaking, he didn't say that they'd feel forced to port the original, he said they'd have to nail it, "probably better than we did with Halo 1 Anniversary." The first bit sounds hopeful, but even bringing up CEA's approach and using the phrasing "probably better" to describe how they'd want to do relative to it is scary. Especially considering that he also said they did a good job with CEA's MP.Phil already said what he said,cant believe people think it wont have it.
It might be a direct port of the original MP, but I won't be all that shocked if it isn't.
More faithful than CEA MP is a low goal.
