Current PS Vita PCH-1000:

Future PS Vita PCH-2000

Judging by the slight alterations, does it matter which version to buy? Nintendo 3DS, Nintendo 3DS XL, and Nintendo 2DS have several alterations that affect buying whichever one, but I don't see buttons being the ultimate factor (Although they say the PCH-2000 will have extended battery life).
