Reasonable on 21 November 2011
I'd guess no.
Sony is is poorest shape in US and being free vs paid is one of the few differentiators they have in the market for online. Unless they manage to somehow push PSN past Live for features charging (while no doubt more profitable) would I'd guess only hamper their ability to try and reclaim market-share in US (and UK too).
There approach with Plus would make more sense to me. I expect to see PSN have cross-game chat, etc. as standard on PS4 with fee allowing basic online, etc. and Plus giving you extended features such the game saves, etc. available today.
Try to be reasonable... its easier than you think...
