The next one comes in 2013. So choose for a long wait, or a perfect computer right now. And it won't give dramatic performance increase. Apple will shrink it instead of make it a lot faster.
Don't make statements that are just your guesses. Your post should read:
"I doubt the next one will come before 2013, so guide yourself accordingly. And I don't think it will give dramatic performance increase. I believe Apple will shrink it instead of making it a lot faster. But keep in mind I don't work for Apple, and have no more information than you do, but like to act as if I do."
It's what Blanka has been stating for the last who knows how long as if it is Fact. Frankly, I haven't seen any "expert" state 2013. All seem to think it is this fall. I think she is just stating 2013 so IF it happens she can be all "see I told you so!"....
4. What happens to the iMac and Mac Mini in the meantime - are they getting a spec bump this year or do we have to wait until next year now?
No t hasn't, though the iMac did a few months ago.Has the next generation mac mini, if there is one, been showing up in any of the Benchmarks? The next generation MP, 13" rMBP and iMac have been, I don't normally follow the Mac Mini forum so I apologize if I have missed it.
I have a feeling that the Mini is dead. The iMac might be on it's last legs too.
