Personally, I'm very hesitant if the release of ICS from LG will work flawlessly on our phone. The upgrade from Froyo to Gingerbread is a small step in technical terms than the upgrade from Gingerbread to Froyo.
So if LG managed to mess up the "simple" upgrade from Froyo to GB, by introducing the infamous ghost-calls bug, I don't even want to think what will happen when they release the ICS rom.
And not to forget, that the ghost-calls issue appeared almost 5 months ago and still there is not an official word from LG. If they are not able to fix a single bug in 5 months, I'm not sure how they can release a brand new rom until September/December.
I'm sure LG will screw this phone even more, it really looks like they just don't care about it anymore.
they're still growing up in the android development path, it happened to sony when they said 1.6 was enough for the x10 and then they upgraded it to gb, they just ported it from the arc but still it had minor bugs
