Reply to buying an s4

Hey what's going on guys? So i've finally gotten enough saved and want to invest in a kontrol s4. Here is my question though, I could order it today (3/28/11) and have it ship in this week/early next week. Or should i hold off until after the first when tp2 is released? Will the release of tp2 change anything involving the s4 such as price, updates, etc. what are your alls thoughts because i'm impatiently waiting now but if it would be wise to hold off then i'll choose to do so. Thanks in advance.
