Looks like my money will be staying in my pocket for a bit longer then.
I really hope that a change of thought goes on soon, if the tyre model can't be completed by easter, (yes, we know and respect the difficulties this has caused Scawen,) then surely it makes sense to release the rest of the content, ie, new track and car plus some other fixes for long running bugs as S3 and then release the updated tyre physics at a later date. The graphics do need an overhaul really, I'm not after GT5 flashy presentation, but 8 year old graphics don't really cut it anymore unfortunately, £36 would net a much better racing simulator than what S3 is currently offering, even if the physics aren't as accurate.
If the devs want to play in their spare time at making the most accurate driving simulator possible then that is up to them, none of us have a right to critisize that, however, if they want a marketable product that they wish to charge people to use, then they have to wise up and alter their priorities a bit. Annual updates are a minimum requirement really, even if it is only cars/tracks or a graphic update, a physics revision or whatever. Leaving people who have already paid out in the cold for 2 years plus is a customer service disaster if you want them to send more money your way in the future.
I'd like clarification from one of the team on which direction they are taking this product, if it's not going to be for the benefit of it's users, then I'm happy to pony up and buy an iRacing subsription to get my racing fix. (I can also race on ovals that way so it won't be too heartbreaking.)
