Based on my own experience working in tech support/customer service call centers, we actually know very little, and Apple wouldn't be too different I would hazard a guess. As if the staff are going to know precisely what's going on in the development department, possibly in a completely different part of the country, on a day-to-day basis. If anything, the rep you spoke to was speaking the truth when they said that there are no planned updates - just means they, personally, don't know about it!
I would put money on, and guarantee that, there will be an update to fix many problems in the near future. It just makes sense. I've got problems too since getting 2.0, but it's just my iPod so who cares. It'll be nice when they fix it but until then, there are more important things going on around you!
