I'm curious... Does direct injection improve fuel efficiency or is it for power?
In theory it should improve both by causing the engine to run more efficiently...they are probably using it mainly for fuel economy though.

Exactly right. I think we can expect a 2TR-FSE and either a 1GR-FSE or 2GR-FSE (already in production). A direct injected 4L V6 could conservatively serve up 310hp and 320lb-ft of torque, while still saving fuel. Hopefully the V6 will finally get the A760 trans (w/ double OD). For the 4 cyl, perhaps the A960 trans can go back into production or a de-contented version of the AA80, like in the FRS, which would be an AA60 of sorts.

What's wrong with that? The El Camino and Ranchero weren't FWD but they were unibody designs.
Funny thing is, the FWD/unibody pickup has been tried before, at least 4 times:
Subaru BRAT, 1979? - 84? (FWD with ability to shift into 4wd. A FWD-only version was sold in other countries but not in the US.)
Dodge Rampage - Mid 80's
VW Pickup early-mid 80's (maybe into the early 90s?)
Subaru Baja, 2004-06 (AWD with a FWD bias.)
I think there is room in the market for a FWD pickup for light duty, and if gas is expensive, they make more sense than even a so-called "compact" truck (for one thing, modern "compact" trucks like the Tacoma aren't all that compact anyway.)
I think all of the other examples except the Baja were introduced at a time (late 70's -early 80's) when gas was relatively expensive. Problem is, as soon as gas gets cheap again, people go back to their big gas guzzlers.
I think the Baja in particular was a victim of bad timing. If it had been introduced even 2 years later it would have come out at the peak of gas prices and would have made a lot more sense. But gas was still right around $1.80/gallon when Subaru gave the Baja the ax in 2005 (making 2006 the last model year.)
Hmm.
I currently drive an 04 V8 Dakota. It serves me well, but I've been looking for something that gets a bit better mileage - the Dakota gets about 14 with my tires. I deploy to Afghanistan within the next month, and I'd planned on using the extra money I'll get for a big down payment on a Tacoma when I get back. I'm a huge fan of the look and reputation.
But now I might wait and save another year. Those new engines sound intriguing, especially for a rig that will be used mostly as a DD.

I'd wait.
Take a look at Ford's direct injection engines w/turbo; the power & fuel economy. Generally speaking, they're pulling about as much horsepower and torque out of half the engine (2.0 Ecoboost) I've got. If Toyota does this right, I'd be concerned about the resale value of the '05-13' Tacomas. We may take a hit.
I think this is the way to go for the next 5-7 years.
This is another nail in diesel's coffin.

Sure, if a unibody, FWD "truck" is what YOU'RE looking for, get one. For my uses, no thanks. The only market this Scion "truck" will attract is the teenyboppers wanting to slam it with airbags and stuff 22's under it.
Right, and how many of those are still being produced today?
EDIT: Oh, wait, let's not forget the SSR

Don't forget the Honda Ridgeline! That may be the longest production unibody truck.

Direct injection technology is nothing to new. Yamaha has been doing this for years with their 2 stroke outboard marine engines.
Direct injection in cars is coming aboard mostly for fuel efficiency and the added alcohol to our current fuel that has caused cars to lose fuel efficiency. With Direct Injection you are injecting fuel with injector directly into the combustion chamber vs in front of the intake valve in the intake runner of 4stroke or crankcase of 2 stroke. You can have more precise injector timing and manipulate the motor more due to not having to wait for the intake valve to open before fuel is pulled into combustion chamber. These systems run an extremly high injector rail psi, some systems in the upward of 650-700psi. This will have to be the future of most vehicle engines to achieve excellent emissions and fuel mileage. Direct injection pumps and injectors have a spendy price tag and mistubishi makes a lot of these systems. If my 4.0l got 25-30mpg that would be cool, I guess.
The problem is our government is trying to go to 15% alcohol in fuel, therefore Direct Fuel Injection (DFI) is going to be required for engines to even survive and get the equivalent mileage as they are getting today.
Government thinking: Cars run on a less efficient fuel currently, E-10, and get worse fuel mileage then non-ethanol fuel, so lets go to E-15 and require that all vehicles made 12 years from now need to get 55mpg.
