Besides new simulcasts for this season I am watching a few other series either through Netflix, Crunchyroll, or Hulu.
I have one more episode of To Heart to watch through Comcast's Funimation On Demand Channel. Since they added one ep a week (sometimes every two weeks) it's been a slow process watching the show but at the same time enjoyed it that way.
Also forever in the middle of renting Urusei Yatsura from Netflix. Currently have disc 16 at home waiting to be popped in my dvd player. I'm hoping that by the end of the summer I'll finish watching the television series and move on to either the ova or the movies. Since I bumped my Netflix down to one disc at a time, instead of two or three like I used to, it may take even longer than that to finish since it's not top priority on my list of anime to rent.
Strawberry Eggs has been in a Netflix purgatory for quite some time so I plan to mix up my queue with this series along with the above. I already watched the first disc in March so hopefully I will finish this series in April. There are a few winter series on Crunchyroll, such as Level E, that didn't end yet so I will be sure to finish those off this month before getting too deep into the spring line up.
