I haven't seen any automated raster to curve tools for Blender specifically. If it comes, it will probably be an addon.
From experience the result of automated tracing on logos, or exact shapes with transitions between curve and corners, is rarely acceptable to closer scrutiny. Invariably they need to be corrected (and optimized). People provide on-line services where you send them a raster image and they send a vector version back.
Blender has OK curve/spline tools to do tracing by hand, I've done this plenty of times. Staying in Blender has the added bonus that keyboard short-cuts are familiar. Filling the spline is also easy and so is extruding. Here's an interesting thread on BlenderArtists where VickyM72 practised on various logos to get a better appreciation of the curve tools.
Many prominent logos are already available as vector (svg, ps, etc..) if you fill their name into a search engine.
