Gaming website Nintendo Life recently spoke to Kingdom Hearts series producer Ichiro Hazama about why the Nintendo Switch ports for the remaining games will be Cloud only.
Hazama stated that there have been various difficulties with bringing over the titles to this hardware, with storage capacity being the only explicitly stated one.
Nintendo Life then asked if Kingdom Hearts HD 1.5 + 2.5 Remix could at least receive a native Nintendo Switch version. Hazama replied with the following statement:
"At this moment in time, the production of a native version is undecided. We believe that the Cloud version is currently the best way to deliver the Kingdom Hearts series to Nintendo Switch players, but we are always excited to hear to feedback from our fans and want to thank them for all their support."
This is undoubtedly a vague answer, but since it isn't an outright 'no,' then it is possible that fans respectfully expressing their desire for native ports will be the key to this hopeful event occurring.
