Looking for some info on possible hardware refreshes

Ok, so I just found out that I will be able to order a whole bunch of stuff in October for my office from a Grant our school got. (I know, its a way off), and I want to get some info on possible hardware refreshes. Here is what I'm looking to get.

Mac Pro
2 x 24" LED ACD
17" MacBook Pro

I just received a new Mac Pro a few days ago from our last fiscal year, which was the 2 x 2.88ghz Quad Core version. Can I expect a new refresh before October on the current specs?

The 17" MacBook Pro that is currently out will do perfect for what I am going to use it for, but I don't want to put in a spec sheet if it will 'possibly' change before Oct.

I don't need to hear the normal stuff, that if I need a notebook now, get one etc... I have a perfectly fine 15" MBP, this is more for a order that is still somewhat off.
