Regarding edges, I've had quite a few of them in my career mode from my bowling to the CPU on Veteran difficulty, probably quite a nice frequency of them, but none have found the slips - they have all been really thin snicks which are comfortable for the keeper or just fail to carry to him.
They still look and feel much more realistic and satisfying though than in any previous cricket game, although there is room for improvement with a bit of tweaking.
I also think that perhaps pace bowling in general should carry through to the keeper with a bit more 'venom' if that makes sense. Apart from with bouncers it seems the keepers take everything very comfortably and at quite a low height. Not really being very specific/descriptive here but I'm trying to be constructive

I'd also like to echo the sentiments of zim and Alberts on this page - this community interaction is excellent. To keep it up after release as well and take onboard so much feedback and continue to support the product is outstanding.
