Yeah there are two types of indefinitely and this is definitely just the "not yet final" variant, not the "don't get your hopes up" variant. If you're wondering what the definite release schedule for the next four months looks like for bigger games it is:
April 10 FFVII Remake
April 24 Trials of Mana
April 28 Gears Tactics
May 28 Minecraft Dungeons
May 28 Shantae and the Seven Sirens
May 29 Xenoblade Chronicles Definitive Edition
June 26 Ghost of Tsushima (This one is screaming delay)
And some ports like The Wonderful 101, XCOM 2, Borderlands and Bioshock collections on Switch, The Outer Worlds on Switch, Death Stranding on PC, etc. After that you have Wasteland 3 at the end of August, Avengers and Cyberpunk in September and that's all. So there's stuff but if things carry on things could get really really dry in July.
I just decided to change this sig.
Blaaaaaaargh
