I'll do the same as I did for this generation, bare in mind how Sony still has all of their awesome 1st party studios, how they've listened to the consumer, not make any snap decisions, keeping an open mind on when companies deliver their presentations, what seems realistic about each new system and judge which to get 1st based on value, options of games and platform features that appeal too me.
So far Microsoft aren't showing that they've learned a thing about what the console market really wants, since Phil Spencer's inception as CEO of Microsoft Studios back in 2009 he hasn't pushed to develop and hire the quality 1st party talent needed to provide quality exclusives for the platform he's now in charge of creating from the ground up.
Nintendo needs to prove they've learned from their mistakes with their next console, so far they aren't appealing to the very market that will bring them back to a dominant position within the console market, but they at least bring the exclusives throughout the generation and they don't charge unreasonable amounts of money for their hardware, so they will definitely be one to look at for a secondary platform.
Anything can change in the console hardware and games market, as Sony showed back in the PS1 days, but really I think Sony are the only ones that truly understand how to tackle the market, by actually providing the masses with the kind of system and games that they want.
