Manthan Vidyashram VS SAN Acaddemy – Velacery – NO CBSE affiliation

Friends,

We are moving from Australia to Chennai, my daughter is 5 ½ year old, looking for grade-1 admission. Since we are moving only in May -2014, we lost the chance of applying for major schools like DVA, CV. We are able to get assurance from Manthan-Kottivakkam and SAN – velacery . Both of these schools do not have CBSE affiliation still, will it be big issue if we decide to move to different CBSE schools in coming years?

Second question which is good option? any help highly appreciated
