ME3 Xbox - PC profile same thing? Can I use my unlocks on pc if gained on xbox?

Noooooooooooooo!

I used to play ME3 heaps on xbox (130 hours online showing at my N7HQ) and I just bought ME3 for pc thinking that since all the accounts link up my advancment would be usable cross platform but now am thinking this is not the case.

Can anyone let me know if all that work and time spent on the xbox, which is still viewable on the N7 HQ site can be used for PC online play? I dont see the point of linking them all up to one thing like they have if not.

I really hope I can transfer this stuff as otherwise the game just wont get used and I wont spend any more money on it, but would if I could maintain my progress (ie: ea will get more money from me if I dont have to start from scratch, which frankly I wont do)

Arrgghhhh someone with some knowledge please help!!!!

.... all those rare weapons... those characters... the weekend banners... surely the gamers are not left adrift here! please say it isnt so....
