I have seen alot of the 37G10 and i have to say firstly i thought it was a cracking picture, with regards to blu ray i think it is alot better than sky hd pictures,
I think the Sony 360 is a great player, and has had some cracking deals including free blu rays.
Also 3D is coming on the new models see here a good deal, i thought

So you would be covered with that.
Also there are quite a few home cinema systems coming out soon like the pansonic one you were looking at, sony are doing some with 3D capabilities, I also expect pioneer will annonce some soon as well.
I would look at the new home cinema all in one systems coming out in the next few months and see how they review, if you wanted to go that route, otherwise I personally think those two sony blu ray players would be great choices.
