Heya Rakehel,
I've always promised to have updated versions of the vBE styles available for download within 2 weeks of the Gold version of a vB version update. Oftentimes it's a lot quicker than 2 weeks.
So, yes. There will be vB 4 compatible versions of all the available vBE Styles. Might take up to a fortnight, but depending on when they release it, might be within a couple of days.
