oh sorry i overlooked that, from wat you wrote (dont think i understand it fully) can i safely assume that the revision in June would be nothing more than just a slight increase in speed and battery, in other words, I should just buy one now..right
I would yes.
But the thing is if Atheros comes up with a WiMAX/802.11n adapter, or Apple decides to use new 5xxx series Intel Wireless adapters that'll be bad luck for you. ( I'm assuming WiMAX will be a good use for you ) But you can always buy an Expresscard WiMAX adapter later.
The other thing is abour RAM. Since there are no DDR3 SO-DIMMs yet, I cannot predict the battery savings using newer tech. RAM.
And of course higher resolution screens woud be nice to see, but noone knows if that's going to happen.
All I'm sure is that the Montvina MBP's performance will be very similar to current SR MBPs.
