I hope they do not rush it. Delay the game if it is not done!
Honestly, Sony's dev kit situation is better IMO (if they launch fall 2006 in the US... Japan can handle a launch with a handful of games). Not availability mind you, but to compare:
PS3 Dev Kit:
-Cell Processor (2.4GHz or 2.8GHz, forget the exact number)
-6800Ultra SLI
-XDR Memory (I believe it was 512MB and now is 1GB)
Downside: 6800 HDR performance weak compared to RSX, Dev kit CELL processor slower than final version, memory bandwidth between GPU<>CPU<>Memory in dev kit is minimal compared to PS3.
360 Alpha Dev Kit
-9800, later X800
-Dual G5s
-Downside: The dev kit GPUs have been a different architecture, lack key features like SM 3.0+/FP10/FP16/Geometry Tesselation, and are significantly slower than Xenos/C1. The Xenos CPUs are In-Order, unlike the G5 Out of Order execution, have significantly less cache which is not shared (G5s had 1MB each, not shared), and in general are very much stripped down compared to the G5, yet on the other hand there are 3 of them and they have beefed up VMX units. The Cache Lock features is also not available, nor the D3D compressions that saves significant bandwidth when the CPU streams to the GPU. And the system also lacks the bandwidth/bandwidth architecture of the final system (UMA with eDRAM on the GPU).
This should not be meant to downplay the importance of dev kits => The SOFTWARE and tools are just as important. And MS dev kits have been around longer and in greater quantity. But devs have also been asked to create games with no ability to test/work with a totally new CPU. Knowing what features are available--and how they perform--is REALLY important when laying the foundation of a game and art direction. Now the ATI Ruby demo running on Xenos is a good indication the chips is very nice and very capable--so I am not too worried for the long term. But in the short term you wonder about the logic of NOT making a chip available to devs early when that chip is very important to the outcome of your games!
Worse yet is the time frame.
Devs have gotten Beta Dev kits in June/July. As Todd Hollensworth noted, they are still underpowered and are literally taking chips out and being asked to put in new/faster chips
Giving them the benefit of the doubt of feature complete Dev Kits by the end of June (and a week or 2 to play with the kit) it seems like launch titles have
Jul / Aug / Sept = > 3 months (October will be the time to go Gold and press the DVDs)
To:
-Get a handle of the new hardware
-Port the code over
-Enable all the graphical features
-Debug the game
-Test, test, test
Basically, their games better be feature/content complete as of June! That is a scary time schedule because it could take 3 months just to port a FINISHED game. These devs are being asked to port a game not yet complete
And then there is the moving target issue. Remember, it was not too much before E3 that the memory got doubled from 256MB to 512MB. Working on a moving target, especially a feature that affects graphics, can really hinder your project. And even up to today they are getting new chips with better performance. How in the world are you supposed to make a AAA+ game when your target platform keeps changing and you have no sure way to test and get an honest feedback on the situation?!!
No doubt PGR3 is a debug version and probably is not running on final HW as they stated. Bizzare is not the only dev making this claim so it is legit.
I just hope if time runs short that the game is delayed.
