My question is not about whether I should get an SSD drive for for my MacBook Pro, it is more along the lines of whether the SATA2 interface on my late 2009 MBP is a limiting factor and whether it makes sense to wait for the next generation SSD drives coming from OCZ and Intel rather than go for something that is current.

In other words, will I see performance gains with those upcoming drives over a current drive, even if my computer has a SATA2 interface?
