It will likely be next year before we see them though

Definatley, but im sure they're worth the wait.

why not 32nm ?
TSMC, who AMD use for their graphics division, won't have 32nm fabs ready yet.

Now the question is if these are the 6 month update for the 4800 series or if these are the DX11 cards?

Be Dx11, they not due till October, i don't think anyway.
Granted, it is the inquirer but still...

ATI won't be launching anything in January, that's more or less guaranteed. A refresh to the current range of cards will be launched over the course of 1H-09, but not as early as January (CeBIT sounds like as good a time as any). That will include a delayed RV740 derivative and a suped-up RV770, which should receive the HD 49xx moniker. GDDR3 and GDDR5 will remain the memory bits and pieces, but ATI has dropped GDDR4 for good... too expensive and too much like GDDR5, said the Cap'n. Now the juicy bit is that AMD has narrowed down the 40nm parts launch to the first half of 2009 too, so between the derivatives and the shrinks there will be plenty of options on the market in 2009.
--------------------------------------------------------------------
Last, but certainly not least, the 58xx series cards will be reserved for Q4 2009 and will pair up with Microsoft's DirectX 11 launch. So fanbois and fangoils, you'll have to wait a while.

So everybody is right.. kinda!
Do you upgrade to the 49xx (Q1 09) or wait for the 58xx (Q4 09)?? I guess it deppends on how desperate you are for an upgrade. I'm planning on my 4870X2 lasting me atleast until DX11, if not beyond... we all know how long it take games designers to catch up!!!

Normally the inq isn't at all bad for this info, the info is leaked out because AMD/Nvidia and the partners won't people to know whats coming frankly.
The only thing is, it seems weird to me they'd release upclocked versions, then a dieshrunk version all within about 2 months of each other. thats a hell of a lot of core tweaking and changing for an incredibly short and expensive run with most likely smaller yields as most new processes get.
Its also very unlikely the new chips would have more shaders/TMU's unless they are dieshrunk. The whole point of redundancy in the chip(read the anand story on the RV770) is they went small and had basically no redundancy.
It takes a lot of time and effort to make new core revisions and costs a lot to tape out. Its always possible and ATi/AMD are at that point where they can afford to throw money around simply to peeve off nvidia and keep very competitive all the time. Logic would suggest they'll only do a 40nm refresh and it would sound like it should have higher clocks and probably a boost to shaders. the 5800 they were talking about said 1000 shaders per core(well they said 5800x2 with 2000 shaders total, 1000 each core) as opposed to 800 now its not a huge increase. the suggested extra TMU's would also suggest a pretty large change of Shaders per TMU which is a fairly big die change, while , shockingly 20% more TMU's (40 to 48) aswell as, lets see 25% more shaders, is a much more "inline" change and makes a lot more sense.
Otherwise we're look at , 4970/50 thats simply slightly faster, then a die shrink but not large architechture change, 2 months later, the 5870/50's, and then 5-6 months after that a DX11 part, so a 6870/50. ALl in one year, which would, with an entire range of cards mean new mid/low end parts at 40nm DX10.1 (5xxx series) and then all new mid/low end DX11 parts end of year. Seems incredibly unlikely to me for them to sell 4 different entire series of cards in 2009.

Also i thought MS had sorted the tech aspect of dx11 so maybe Ati will include it in the next set of cards and get an early jump on nvidia like they did with 10.1. Either should be an interesting year to come and good for us customers that the competition will continue 
.
.Well, GT300 is supposed to be coming out Q4 2009, too, so it'd hardly be surprising that they both launch their DX11 parts at the same time - I just wonder though, I think ATi has a significant advantage in that they're now on their what? Third generation hardware tessellation unit (1: 360/R500, 2: R600, 3: RV770), and that's one of the highlights of the DX11 specification.
They had an advantage of having a first generation unified shader GPU (the Xenos), look how their first DX10 GPU turned out.
