With the Uncharted 4 delay, a PS4 for $299 later this year does not feel far off.

I think Sony will instead try and money hat MGSV for exclusivity through the holiday season and move that further into fall 2015 (October?).

And cut to $349.99.

The system is selling very well, there's no need to panic and drop a full $100, it's just leaving a lot of money/profit on the table.
