It will probably happen, but I don't expect to see it until 2006. We MIGHT see EFI this Summer, but I don't really know. And if we did, no way would I buy it. Yamaha is notorious for using its customers as testers and not acknolwedgeing problems until way late. It took them two years to admit to the fuel boiling problem in the Grizzly, and they have yet to do anything for 2001 Raptor owners with blown transmissions.
In addition, we're at the practical limit in the size of a single-cylinder motor. Much bigger and they'll have to go to a twin, which I don't want because it will suck a lot more gas. Just look at the Sportsman 700 and Prairie 650/700 machines. They get about 20-25% worse fuel economy than the Grizzly.

Check out the thread I started titled 05 Grizzly and it should answer all of your questions from the information I got.
Fuel boiling problem? I have a 04 griz bought it about a month ago, the first hot day, like 80 degrees I was doing some trail clearing and I experienced a problem with driveability, call it vapor lock or whatever, all I know is the engine temp. light never came on but it sure was throwing off lots of heat and was running rough until I ran it down the road for a while, lots of gas fumes also until it cleared its self out.

Yep that's what you experienced, danny. Good ole fuel boiling. Nice to see that Yamaha is still NOT correcting the problem.
The next time it happens, remove your left side panel and stow it. Don't forget to remove the plastic fuel valve knob or you may never see it again. That should vent enough air out of the engine compartment so it'll behave. It's ugly, but at least it works.
