Buying Macbook Pro 15" 2.53Ghz?

[Asnyers]

I'm planning to buy a new laptop and there's is this offer on the previous macbook pro (the one before the March revision)

I save 200 euros when I buy the previous model and as money is an issue this looks appealing. What are the big differences performance wise? I can see there is a small difference in processor speed, but that won't be really noticeable will it? Are there any other differences I'm missing?
Also, what's the chance we'll see new macbooks this summer (June)? Will there be any new hardware that will make me regret my choice? I can wait till August if needed.

Thanks,

Asnyers.

If your gaming or doing a ton of video go for the current model. Older model is still good for a lot and will most likly be worth the savings!

If I'm not mistaken, the 2.53 model he is talking about is a unibody MBP.
The only difference between that model and one off the shelf today is .07 processor bump

Does the 2.53 take 8 gigs? I mean, it's not like most people will use it, but still...

Not currently, but we're hoping for an update.

Apple's hoping that you'll buy the new model instead.
