It's cool, as long as the products stay tight. I seem to remember that J-Diggs said in an interview that this was MD's plan all along--he already had most (if not all) of these artists signed before his death and was going to invade the market w/ multiple CDs both by these artists (Rydah, PSD, Bavgate, Mistah Fab, whoever else) and himself, as well as doing comps. The way Diggs explained it, MD wanted to make better opportunities for Bay rappers to unify and get their shit out ASAP. He wanted Thizz to create a "network" in the same vein as many of the Down South rappers do w/ their music.
So, my guess is that (with this year's releases, anyway) Thizz is just carrying on what MD was planning to do had he survived (except, of course, for any solo MD stuff--obviously, only MD himself would know how he wanted his own solo CDs done). As far as anything that might come out next year and thereafter--well, we'll just have to wait and see. Hopefully, MD's name won't get pimped for garbage the way Tupac's name (in recent years) has since his death.
PEACE!
