While there's been a mixed reception from Xbox fans so far regarding Microsoft's continuing multiplatform efforts, there's definitely one nice bonus to some of these games having an extended shelf life - massive free updates for the existing Xbox versions.
Yep, next month, both Forza Horizon 5 and Age Of Empires 2: Definitive Edition are getting some of "the biggest updates" they've ever done - as they prepare to release on PS5. FH5 has already set an April 25th date for its 'Horizon Realms' update & early access PS5 launch - while AoE2 is plotting a "mid-April" date for its next massive update, and presumably its PS5 release as well.
