I think it's an interesting question, as there are a lot of us investing in 2.5" SSDs to place into our non-retina MBPs. I suppose you could still utilize the drive in a USB3/TB external enclosure but it would be nice to be able to reuse in a future installment of the MBP.
Of course you can never know, but if you were to speculate: Will Apple phase out the non-retina MBP next year and move forward with the non-upgradeable, proprietary design of the MBPR? Is 2012 the last year of the "customizable" Apple laptop?
