As far as I'm concerned it will be released. In DOHC 24valve form, single turbo running about 5-6 pounds boost and 210-220kw and 430Nm. It will not only provide a much needed "boost" for the 4.0l six, it will be huge in the aftermarket arena as already mentioned, particularly in a few years time.
Do the maths, it's gonna be better than you think :)
Based purely on boost numbers alone (with 100% volumetric efficiency, 100% intercooler efficiency, etc) 7psi (half atmospheric pressure, turns your 4 litre I6 into a 6 litre I6) acting on a 180kW inline six could add 50% more power to the whole equation. 50% of 180 (assuming base model twincam six is 180kW) is 60, so that'll be 240kW. This isn't taking into accound other things that could (would) rob power from the whole shebang..
However, for the mods guys out there, add a decompression spacer gasket (as easy as changing the head-gasket), nuke the boost up to 14psi (easy too - ask any ricer out there :), and you'll have a near-factory DOHC Falcon that'll leave 90% of other 'performance' cars for dead!
Of course, forced induction increases volumetric efficiency, so it could well be better than that!
I just hope it doesn't turn out like VCT, that was such a disapointment, and it was all marketing.. BLAH!
I see the six cylinder engine range as:
Ford engines:
4.0 SOHC 160Kw Base engine
4.0 DOHC 180Kw enhanced engine
4.0 DOHC 215Kw Turbo XR6 engine
Tickford T engines:
4.0 DOHC 206Kw Naturally asperated engine
4.0 DOHC 250Kw Twin Turbo T series engine
Fords SOHC 160Kw engine will allow for low price points for Forte, Futuras, plus make a incentive for private buyers to pay more for the power hike. Also for the base ute. LPG options say.
The DOHC engine will be avalible in the XR6, S/SR (s is for sleeper?), Fairmont, Fairlane, LTD.
The DOHC Turbo engine will be avalible in the XR6, Ghia, LTD.
Why does tickford need a hot naturally asperated 4.0? Well basically because some people aren't allowed to buy forced inducted engines or V8's by company policy or by evil insurance people. Plus it will be eventually handed down to regular XR6's with in ~5 years (maximising R&D). The 206Kw is a realistic target, obviously targeting japanese car makers. Plus with out a turbo, it can still compete with the HSV XU6 which really is the weak link in the HSV line up, it could attact alot more buyers.
The Twin Turbo is not a XU6 competitor, its something that Ford is going to pioneer against holden. A real six cylinder contender.
I envisage two markets for this car:
-Export to UK and Japan (if made in LHD middle east, contentental europe), should be fitted standard with a 6 speed gearbox, biggest brakes and wheels possible. Its smaller engine (smaller than a 5.0/5.4L/5.7 V8) will win favour with enthustists, as will its inline configuration. The figures are magic, in the UK the i6 DOHC and the power number will bring up visions of a TVR, in japan its Skyline, olde style. Remember they did make some 2.6L Twin turbo FOUR door GT-Rs in japan.. its not a volume seller, its marketing. Charge outragous prices.
-Local consumption. 5 speed will do fine aslong as its smooth. Perhaps just normal brakes will be needed. More lairy bodykit etc. Realistic price tag. Its designed to compete against cultured six cylindered cars, but diffrent.
I don't see high powered 6's and 8's really crossing. Each has benifits and disadvantages. High powered 8's will appeal to paint your chest and drink a Vb, V8 fantatics, and high powered 6's will appeal more to the toffee nosed aristcrats with fat wallets and leather recliners.
Either way, its all new market share to Ford.
I think the only problem would arrise is if either the V8 or the I6 couldn't cut the mustard. Then you have a imbalance in the force.
I think any naturally aspirated ford six must beat the commie super charged S for both price and performance so the XR6 regains the price performance combination which made it so attractive in the first place.
well, if ford is to win some sales, it'll have to be more refined and more powerfull than the holden.
what Iphido said makes sense to a certain point, but i don't know what can be done to make the 4L more efficient as it is, without the dohc. maybe they'll fit it with dohc and detune it just to get lower fuel consumption.

Guess we'll have to wait & see. The I6 has always been a big producer of torque over power, so it will be interesting to see how Ford decide to use multivalve heads & forced induction.
Can't see how they are gonna get it to rev but I've been surprised before!
