I'd say Wolverine: Origins is the actual prequel to the X-men Trilogy (whether you like it or not).

Hugh Jackman has such a minor role in First Class that you could probably ignore it, if you wanted to treat it as a reboot. And frankly, there is no law against casting the same actors in a reboot (except that it makes it confusing). But it cannot be a reboot, because The Wolverine is set after Last Stand. That would be a first - to reboot the series and than to go back to it. It was probably meant to be a prequel, but the writers got carried away.

I think the only way to stitch it all together would be to make this parallel realities. That would allow for some stuff to be the same and some to be different. But will see how it works out in DoFP
