I would have to agree on Macrumors track record as of lately.
As for the mysterious xstation, who knows -- One thing is for sure, I have to agree with with blitzkrieg79 on Apple's line up becoming outdated especially with the Powermacs. The iMac and mini have some life left but it is unkown how far performance can be pushed with their current designs.
Apple needs to shake up their computer lineup to respark the public interest. The iPod has done an excellent job of making people aware that Apple still exist and now that eyes are on them they need to sink them Tiger teeth a little deeper with an all new line-up.
By the end of this year, Intel/AMD should be in a position to push dual-core versions of their chips. Apple will probably go with dual-core before the cell-processor (if they do cell that is). If Apple offers dual core they should at least keep the current processor line-up the same (i.e. mini,eMac,iMac, have 1 dual-core processor and Powermacs have 2 dual-core processors). The reason being that Intel/AMD probably will not be able to match price/performance that the PowerPC architecure has (since all the game consoles main processors are coming from IBM -- all that mula IBM will be making will only further PowerPC/Cell technology.
My opinion on whatever Apple does -- they better do a few things if they want to entice me to by another Mac: Make it smaller or even better looking, Must graphically WOW me over my new cheap game consoles (well at least better than X360 anyways) be leaps and bounds faster than my current Powermac Dual 2.5 GHz ( come on Apple, only a small speed bump from last generation. I can upgrade my current mac with a new firewire drive or DVD drive for Cheap (and faster), or spent the money on more memory.
I still wish apple would recognize the fact that there are lots of people out there, like me, who need and use a lot of processor and GPU power but don't need the expansion capability or the price tag that comes with Powermacs. I would be a happy camper if Apple had released an Top Model iMac with a 6800 ultra (I do alot of graphic oriented work and love gaming). I believed they could have pulled it off at around $2500 price tag. I have not, and probably never will, place anything other than a graphic card in the available PCI slots on my Powermac.
Hmmm guess I'll just have to keep on waiting and wishing
