It is beyond absurd for you to claim that Retro Studios is "wasting resources they clearly need on their own projects" when the president of the company says the exact opposite. Are you privy to the company's inner workings? Do you somehow know more about them than their own president? I'm having an extremely difficult time taking your claims seriously in light of staggering evidence to the contrary.
I don't believe the extra bandwidth Kelbaugh spoke of could have contributed to getting Tropical freeze out faster. If a construction company employs painters, they can't paint until the walls are built. In Retro Studio's case, my understanding of the Kelbaugh quote is some of those people don't have anything to do until the game is far enough in development to give them something to do. In the meantime, they can pitch in and help different game's development.
And it is equally absurd for you to state that those extra people could be working on a game "that actually excited people." What does that even mean? Making blanket statements about how people feel about Retro Studios' games, particularly when the general consensus suggests otherwise, strikes me as especially ridiculous.
