[I don't follow the logic here. The old way would have had us pay 150$ for X4 and we would then have received X number of updates until X5. With the new system, you pay 150$ and you get 'X4' and 12 months of updates. I don't see us getting an X5 for free as that will be contained within the next twelve months for which we have to pay an additional 200$.
No, you don't have to pay an additional $200. The $150 you pay now gets you X4 and feature updates, not just patches, for a year. The updates and content that would have sat on the shelf after being developed over the next year would have become X5, but instead, you'll get them as they become ready for prime time over the next 12 months.
Think of it like a magazine. When you pay for a magazine subscription, you don't pay for what you already received, you pay for what's coming up in the future. And like a magazine, you get to keep it.
