Well looks like we are finally getting it but . . . it would be wise to wait for it to go down in price. I have played this DLC on the Xbox 360 and it was pretty disappointing or in my case rather annoying. From here on out though all the DLCs for New Vegas will be coming on the PS3 simultaneously with the Xbox 360 and PC. Looks like Bethesda Softworks is going towards the right direction for once.
