Making things pep8-compatible is definitely a priority (meaning there are some issues to fix on organize imports and code-formatting). However, as Appcelerator is no longer backing it up, I'm not really doing active development on it right now...
I've created a funding campaign at http://igg.me/at/liclipse
to keep on supporting it properly (so, hopefully it'll succeed so that I can keep on working on PyDev -- if you work on a company that uses PyDev, it'd be nice if they could sponsor that effort).
p.s.: I'm on the process to setup a new tracker for PyDev so that those issues can be reported and voted on, however, it's still not live (so, please buffer the requests -- I'll announce it at the funding campaign once it's live).
