EDIT Yes: 3 months before international units with 3G, but no international data plans until June/July - slightly shorter than iPone but still US only initally.
"iPad will be available in late March worldwide for a suggested retail price of $499 (US) for the 16GB model, $599 (US) for the 32GB model, $699 (US) for the 64GB model. The Wi-Fi + 3G models of iPad will be available in April in the US and selected countries for a suggested retail price of $629 (US) for the 16GB model, $729 (US) for the 32GB model and $829 (US) for the 64GB model. iPad will be sold in the US through the Apple Store® (www.apple.com), Apple’s retail stores and select Apple Authorised Resellers. International pricing and worldwide availability will be announced at a later date. iBookstore will be available in the US at launch."
No international prices yet, no international data plans for six months, no international e-book store; yes, you can get the Wi-Fi model at the same time as the US, but I wouldn't say you're actually getting the same product if the connectivity and content are the main thing (and I'd compare the sales of the iPhone and iPod Touch to say that the connectivity is pretty key).
