Macbook and Diablo 3

I'm pretty pumped for Diablo 3 to come out, but my Macbook isn't up to par with the new specs. They are currently listed at:

Mac® OS X 10.5.8, 10.6.2 or newer
Intel® Processor
NVIDIA® GeForce® 8600M GT or ATI Radeon® X1600 or better
12 GB available HD space
2 GB Ram
DVD-ROM drive
Broadband Internet connection
1024X720 minimum display resolution
Mac Recommended Specifications:
Intel® Core 2 Duo processor
4 GB system RAM
NVIDIA® GeForce® 9600M GT or ATI Radeon® HD 4670 or better

My Macbook's specs are: Model Name:
Model Identifier: MacBook2,1
Processor Name: Intel Core 2 Duo
Processor Speed: 2 GHz
Number Of Processors: 1
Total Number Of Cores: 2
L2 Cache: 4 MB
Memory: 1 GB
Bus Speed: 667 MHz
Boot ROM Version: MB21.00A5.B07

So my question is, what should I/do I need to upgrade to be able to run the game, and how much am I looking to spend in total.

Thanks in advance, I appreciate it.

You're pumped? Blizzard hasn't even officially issued a release date for it yet. Is there new news?

I heard it will be out in the third quarter in 2011. Any thoughts on my current specs and the ones for the game?
