If "Zestiria" gets enough pre-orders it could become a bonus
The upcoming Tales of Zestiria was confirmed for PC in addition to PS4 last month, and now 2003's Tales of Symphonia is also set to get the PC treatment. Based on last year's HD version, Tales of Symphonia is coming to PC via Steam sometime next year.
There aren't too many details at the moment, but those who pre-purchase Zestiria on Steam could have an opportunity to get a free copy of Symphonia HD when it launches. Pre-purchase bonuses for the former ultimately depend on how many people plunk money down, so if enough folks pre-order the bonuses will increase.
