If by patches you mean unofficial fan patches, maybe. How many patches did Oblivion get? One?
Pretty much, yes. And, as you know, the unofficial fan patches fix more than a thousand additional bugs.
In IRC last night, a friend told me he played Oblivion with just the official patch, but had to use the console to "cheat" around quite a few script bugs in order to finish bugged quests, etc.
So, I would have to conclude that, no, Bethesda does not waste any love on a product once it passes its sales peak. Based on past performance, we can assume they will fix the worst crash-and-burn bugs with a beta patch "pretty soon", and eventually declare it a "release" patch, after which they will wash their hands of the product.
This discussion has got me playing with Oblivion, and one thing that does strike me about it is how many things seem to be influenced by Fallout... tag skills, talking heads... I mean the whole genre was influenced by it to some degree. So maybe the "Obliv with Guns" thing isn't just designer laziness, but maybe they were going for (what they perceive as) a Fallout feel in (some aspects of) Oblivion the first place. Did I mention that I digress?
