Hi Harry,
I know how you feel! I feel that way about Andy Garcia, if he is in GFIV. Only, I know I will see it, I'll just be disappointed.
IMO I'd rather see DiCaprio in it then Garcia.
On the optomistic side however, maybe, if we are very lucky it will be made, be fantastic, and we'll all like all the main players, whoever they end up being.
