I can't see it happening with the numbers we have. There are something like 50 reasonably active live players. If the average player does three new teams a month, that's less than $2000/month before taking any 6-pack discounts, credits and rewards into account. So maybe $1200/month gross. If they were to pay a programmer a dirt-cheap tech salary of $50/hour, that's 24 hours a month they could devote to Live before losing money on it. The Live game is programmed in an old version of Java, and WIS has said no one working there has the experience with that old code to go in and tinker with it. To make any changes, they'd have to re-code the game in a more-modern language. They'd have to set up a testing system and server, plus however many hours of programming it would take. I have no idea how many hours that would be, but even if it were 100 hours, that alone would eat up four months of gross revenue. Testing/troubleshooting would be at least another 100 hours and four more months of gross revenue. It would be a tough sell to walk into some low-level FoxSports exec's office and make the case for spending 8 months' worth of gross revenue to redesign a game that 50 people use. Or 100 people.
They're putting resources into HBD because there are multiple hundreds of users. If you're Fox, why would Live be anything other than the lowest priority? At some point Java will become unuseable, and at that point they pull the plug and don't even notice the $1200/month.
It might make sense at that point to sell the game to some individual programmer for whom trying to double or triple revenue would make transporting the code worthwhile. The problem with that is a new owner would not have the rights to MLB players through FoxSports' deals with MLB, so it would probably not be a viable option. Fox keeps the game going because it's minimal work to bring in a tiny profit; maybe an hour of support work a week across all of Live. When it becomes a big project, it seems unlikely that they'd expend much effort for the amount involved.
