I disagree but then again i'm a newbie. As far as i am concerned with what i know happens PC side i reckon that
1) There is too close a relationship currently between iMac and PMac. Thinking logically this must be hurtin apples's creative market.
2) Windows XP .... and microsoft and intel and AMD etc... (i do not like them except for AMD) will and are trying to attack the creative market that was traditionally owned by apple e.g. photoshop market. If apple doesn't push their nose out the door now with ew technology they could find themselves loosing a significant market share to Dell Intels running Linux. Where i work part time... they just bought in 14 new Dell workstations running Red Hat Linux instead of new apple towers which they were replacing... reason for this..... boss wanted up to date hardware and despite my encouraging him to go apple it made "no logical sense " to him...
3) Apple have pledged to go after other markets such as 3d modelling etc... they have Maya (fantastic) at the moment... but... in all honesty they do not have comparable hardware to the PC side of the fence to run this app on.
4) The pc side is advancing very quickly to 64 bit processor and the speeds of 32 bit processors are progressing extremely fast.... Moores law does not seam to apply to apple..... or to be fair to Motorola!
5) Apple is currently targeting PC folk to switch. Perhaps that is why we are seeing great apps like MAYA showing up on OS X. Unfortunately the people 'switching' from pc to mac will be comparing, how the speed of these professional apps compare to their prior PC version. In maya's case the PC version is supposedly substantially faster with single AMD XP2200+ compared to a dual G4. Imagine what a PC switcher would think if moving from a dual AMD to a dual g4 with MAYA. it would not look good. I am sure that there are other significant apps that need more power also. A speed bump and DDR would not be sufficient to close the gap with the X86 platform which is growing by the month.
6) It seams like typical corporate strategy apple is playing .... the past 8 months have allowed them to sell off old stock.
7) It is unlike apple to ignore a product as long as they have without releasing a new product. Power mac has been ignored for last 8 months.
8) Historically the Power Macs use a newer generation processor than the Imac.
9) Apple is aware of all this.
Finally just because we hear about a new 'G5' type processor from IBM now does not mean that apple has only been made aware of this now.... its likely that they have been prepping for a launch since last year
Again with the PC side moving to 64bit and gaining hype for 64bit computing "Opteron", "Itanium 2". For advertising sake apple need to get a 64bit part out the door ASAP.
Again this is just my two cents worth...... but i think it would be a financial disaster to the PowerMac line (which is extremely important to apple) for them Not to introduce a new G5 line sooner than later. I would be fairly confident that we hear an announcement before the end of the month about the IBM Power 4 derivative in a new G5 powermac. That pic with the massive heatsink was fairly telling. Coupled with the fact that apple would be highly aware of all of the points that i made above and would want to rectify many of them. The most logical thing is that with in next two months, possibly launched at Mac World Paris in October there will be a G5. It seams like its a good time to jump on the apple bandwagon. Apologies for the length of this post, thanks for reading. And educate me where necessary i dont claim to be gospel!,

P.S. don't forget that apple Australia were on their website "welcoming visitors to see their newest technology" i think in september..... hmmmmmmmm ... pst.....(whisper)...g5.....
