First: no new iMac, either Merom or Conroe, would be hotter than an iMac G5 or even a Core Duo.
Second: The "new form factor Mac" doesn't exist, and will not be launched unless Apple decides to make a new Anniversary Mac.
The headless Mac is rabidly desired by a select few here in MR, but has no bearing whatsoever on the normal and SMASHING majority of consumers out there. The need for expansion has always been a lame excuse, especially when you can do practically EVERYTHING with an AIO Mac.
FW is there, USB is there, mike/cam/speakers are there...want more? There is a very good GPU which is enough for years to come. There is a HD with 250Gb, more than suitable for any average user. And there is enough speed to go through any task in no time. Sorry, almost nobody needs a double-SLI card or a fiber channel interface...
Apple is wise in following that path, instead of bowing to a few crazy geeks that have no clue about market strategy. It has suffered the Performa/pizza box syndrome before, and the headless Mac would be no more than a redux of that, sorry; it would pose a dilemma on every consumer out there, confused between a great AIO desktop, a reasonable box, and an expensive tower.
EDIT: By the time I finished writing my rant, sigamy and Spagolli94 said pretty much the same thing. My apologogies for the repeat.
I have to agree with you that the average non-gaming Joe will be pretty happy with an iMac. If Apple can fit a decent graphics card in a soon-to-come 23-inch iMac, it could also satisfy the demands of a large number of gamers. Like many here, I assume the iMac will switch to a desktop chip when they replace the Merom, so it will probably become an even more kick-ass machine around the time Leopard is released. By that, I mean
relative to the rest of the desktop market. (In the meantime, with Merom, I assume that gamers will prefer something else, but not everyone is a gamer.) And if you already have a screen, Apple will basically be upselling you to a dual-screen system if you keep the extra screen and connect it to the iMac.
Sure, eventually, you'll upgrade and you'll have to find a way to recycle it, but since it's an all-in-one, I think it's much more likely to find some use somewhere than a headless PC whose screen has been stolen by a younger sibling. I've given my not-so-old iMac G5 to my parents and it should serve them well for the foreseeable future. If I had another one to get rid of, I'm pretty sure it wouldn't be too tough to find buyers: Macs are built to last, and not everyone needs the latest and greatest hardware.
So, in conclusion, I guess the gap between a Merom-based iMac and the Mac Pro is pretty big, but Merom's replacement should close it enough that Apple won't feel the need to offer an in-between model. Apple
could easily offer a Mac Pro with only one Woodcrest, but the existence of a less-than-quad Mac Pro would take away from the aura of power that the Mac Pro has at the moment. Sure, quad-core is too much for most people, but I think it's part of Apple's branding effort, i.e. if you get a Mac Pro, you can be sure that it won't suck.
