The specs for Castrol's 'real synthetic' Formula R 0W40 are interesting. cSt @ 100C 12.9, @40C 73.6, CCS @ 35C 5,200, HTHS 3.6, Pour point -54C, TBN 10.3. A3/B3/B4, MB 229.3, BMW Longlife, Porsche, Rolls Royce, VW 502.00, 503.01, 505.00 and get this Team Toyota Europe. I'd bet this would be a killer LS1 oil. 12.9cSt is the lowest 40W I've seen and great for those in NA who panic when they see 40W on anything. How long before this appears on shelves in NA I wonder??

I like the sound of this oil, I think it would be great in the LS1 and LT1 engines. I doubt it'll arrive here though.
Those are roughly the same specs as Motul 8100 0W-40. 100% Synthetic, Ester based.
My prediction is that Mobil 1 0w-30 R will become the mass market leader and replace the hard to find GC. I wish I could say for sure that GC is here to say or what it exactly is, but I can't. I'm very glad though to see another huge oil company role out a high end oil.
Dunno why everyone is so heart bent on the GC stuff .... if you can't get it anymore, just get some Amsoil 0W-30 for the winter and 10W-40 for the summer and you never have to look back and cry a tear over the GC stuff .... I for once believe that we will see the GC stuff slowly replacing the US made Syntec 0W-30......but still then I think the UOAs show that Amsoil can keep up nicely
