I think there will be a unified OS with different form-factors. Some games will be exclusive to certain form-factors, but others will be multiplat. Iwata has been hinting heavily at it. Third parties can just port games to the more powerful form-factor.
Well thats exactly the question though cause how powerful will it be? The more powerful form factor which, lets just call it their console, has to be close enough to the ps5/x2 or else the third parties won't do it period.
