Has Nintendo ever had two successive generations of success when it comes to hardware install base? Seems like they're always hot and cold with hardware sales since the NES, but pretty solid with software.
If history repeats itself the Switch 2 may falter behind if it's just a Suped-up Switch with not much else going for it.
With Sony, it's clear they're returning to the handhold market according to the Bloomberg report from last month, and after the success of the Portal, they'd be stupid not to capitalise on it with a hybrid console/handheld + multi-SKU model for PS6.
Next generation will be a battle of philosophy, where the winner will be decided by how the market shifts. Will they go full digital with Microsoft's 'everything is an Xbox' strategy, or will they stick to what they know with mobile gaming & dedicated consoles?
