37 Signals are masters of generating a buzz about their applications, and there’s no better example than the way they feed users of their various applications previews or teasers of features they are working on.

They built anticipation of Highrise up to fever pitch, and only 30 days after that product’s launch they seem to be turning their attention back to their flagship product, Basecamp.

But what was most interesting about the article on their blog was the screenshot (below). The title of the site is clearly marked as Basecamp 2. 37 Signals wouldn’t have put that there if they didn’t want to tease you.

So, I think we can safely assume that Basecamp is coming up for an overhaul. Lets just hope that overhaul includes some much needed integration with their other applications such as Highrise.
